[U-Boot] [PATCH v4] mpq101: initial support for Mercury Computer Systems MPQ101 board
Mpq101 is a RapidIO development board in AMC form factor, featuring MPC8548 processor, 512MB of hardwired DDR2 RAM, 128MB of hardwired NAND flash memory, real time clock and additional serial EEPROM on i2c bus (enabled). USB controller is available, but not presently enabled. Additional board information is available at: http://www.mc.com/products/boards/ensemble_mpq101_rapidio_powerquicc_iii.aspx Environment is configured to precede the actual u-boot image so that it's located at the beginning of flash erase block (made necessary by the recent changes to the embedded environment handling). Signed-off-by: Alex Dubov oa...@yahoo.com --- Changes for v4: - Replace config.mk supplied linker flags with custom linker script. - Fix checkpatch errors. Changes for v3: - Use io accessor functions for all mmio accesses. - Add configuration options for RTC and EEPROM on I2C buses. Changes for v2: - Remove some stale configuration code from board initialization functions.

Re: [U-Boot] [PATCH 2/2 v2] mpc5200, digsy_mtc: add support for rev5 board version
Hi Heiko, difference to previous board version: - M29W128GH flash from Numonyx - SDRAM ISSI IS45S16800 (Option A2 105°C) - rev5 uses RTC RV-3029-C2 - update cs0 and cs1 baseaddr and length depending on the detected flash size. - added Werner Pfister pfister_wer...@intercontrol.de as maintainer for the digsy board variants - As the M29W128GH needs a special flash_cmd_reset() document that in the new file doc/README.cfi. - move #endif /* CONFIG_CMD_IDE */ to the right place - remove LOWBOOT config option for digsy_mtc and digsy_mtc_rev5 boards - change doc/README.cfi as Stefan Roese suggested Signed-off-by: Heiko Schocher h...@denx.de Signed-off-by: Stefan Roese s...@denx.de cc: Wolfgang Denk h...@denx.de cc: Stefan Roese s...@denx.de cc: Werner Pfister pfister_wer...@intercontrol.de cc: Detlev Zundel d...@denx.de Acked-by: Detlev Zundel d...@denx.de Thanks!

[U-Boot] new board with common code
Hi I'm adding a new board. It's very similar to freescale's P2020DS, that's why I used this code as starting point. The problem is now that it still uses some code from board/freescale/common. At the first try this didn't get built and therefore I get link errors. What's the preferred way in this case? - Is it allowed to use sources inside another board/vendor? - Is it better to link to it or should I just copy the files into our vendor or board directory? - If it's okay to link to objects from another place, how can I adjust the makefiles/config.mk so the freescale's common lib is built as well? I know makefiles but u-boot is quite high level usage. Once we have it adjusted and running I will create a patch to have it added to the official version. Thanks bye Fabi ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Dear Fabian Cenedese, In message 5.2.0.9.1.20110114115035.036b5778@localhost you wrote: I'm adding a new board.

At the first try this didn't get built and therefore I get link errors. What's the preferred way in this case? - Is it allowed to use sources inside another board/vendor? It is allowed, but not recommended. You are running the risk that the board vendor may make arbitrary changes to his board code, which may work fine for him, but break your board. And you cannot even blame him, because he probably is not even aware that this code gets used by others who rely on it. It is recommended to move such code to a common directory. - Is it better to link to it or should I just copy the files into our vendor or board directory? Please do not copy any files. Duplication of code is the worst that can be done in such a szenario. - If it's okay to link to objects from another place, how can I adjust the makefiles/config.mk so the freescale's common lib is built as well? I know makefiles but u-boot is quite high level usage. Before we go into details we should define a strategy. Can you please be specific: which exact files are you talking about? Then we can dicuss with the Freescale guys how to handle this situation.

The board boots from the NOR flash. Following devices
are supported:
- two ethernet devices (FEC and SMC911x on debug board)
- I2C
- PMIC (MC13892) via I2C interface
- UART
- NOR flash (64MB)
- NAND flash (2GB)
- basic access to mc9sdz60 registers via I2C interface

The issue is mem_ctrl_asm_init redefine in
arch/arm/cpu/arm1176/s3c64xx/cpu_init.s.
At first, the link script file include cpu_init.s in
board/samsung/smd6400/u-boot-nand.s, If I separate the cpu_init.o from
COBJS-$(CONFIG_S3C6400), I guess cmd_link_o_target will deal with
cpu_init.o. So the link script will double link the cpu_init file.
I have two method to solve it.
first: see the patch
second: Modify the link script
But I feel, the first method is safe.
I asked a question. I will RR on next, The patch1 and patch3 have
already ok, Do I only send patch2 and patch4?

Re: [U-Boot] new board with common code
I'm adding a new board. It's very similar to freescale's P2020DS, that's why I used this code as starting point. The problem is now that it still uses some code from board/freescale/common. At the first try this didn't get built and therefore I get link errors. What's the preferred way in this case? - Is it allowed to use sources inside another board/vendor? It is allowed, but not recommended. You are running the risk that the board vendor may make arbitrary changes to his board code, which may work fine for him, but break your board. And you cannot even blame him, because he probably is not even aware that this code gets used by others who rely on it. It is recommended to move such code to a common directory. - Is it better to link to it or should I just copy the files into our vendor or board directory? Please do not copy any files. Duplication of code is the worst that can be done in such a szenario. - If it's okay to link to objects from another place, how can I adjust the makefiles/config.mk so the freescale's common lib is built as well? I know makefiles but u-boot is quite high level usage. Before we go into details we should define a strategy. Can you please be specific: which exact files are you talking about? One thing was pixis, but as we don't have that FPGA I could remove all references to it. Also missing was the eeprom so I got a link error for mac_read_from_eeprom. We mainly want to use U-Boot to initialize the CPU and DRAM. As this is a PCIe-card for the PC we can then download all other things we need. So I could also remove the EEPROM support. I cleaned the config file up and removed things we don't have. I can now build for my board without using anything from freescale/common, so the problem is solved for now. I will think about it if we need to add something and the error comes up again. Thanks for your help. bye Fabi ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Thanks for your help. bye Fabi Ok, I'd be surprised if you need anything in freescale/common - k ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

[U-Boot] [PATCH 2/2] powerpc/85xx: Add Support for Freescale P1014 Processor
From: Poonam Aggrwal poonam.aggr...@freescale.com
The P1014 is similar to the P1010 processor with the following differences:
- 16bit DDR with ECC. (P1010 has 32bit DDR w/o ECC)
- no eCAN interface. (P1010 has 2 eCAN interfaces)
- Two SGMII interface (P1010 has 3 SGMII)
- No secure boot

Re: [U-Boot] [RFC] ARM: mx31pdk: Use the new relocation scheme
Hi Stefano, On 1/13/2011 11:38 AM, Stefano Babic wrote: On 01/12/2011 01:49 PM, Fabio Estevam wrote: Hi, Hi Fabio, I am trying to make the new relocation scheme to work on the mx31pdk board. With this patch applied the mx31pdk build works, but not able to get a U-boot prompt yet. I have tried to imagine some issues, but I cannot find a clear reason. Building with your patch I checked that nand_spl is still less than 2KB code, and that matches the NAND page, as required by i.MX31 - so it is not a problem. Have you tried to disable the relocation, just to check if the relocation is an issue with CONFIG_SKIP_RELOCATE_UBOOT ? This is not a solution, but only to check what happens. Yes, I tried to disable relocation and U-boot still fails to boot. I copied the nand_spl/board/karo/tx25/u-boot.lds to the mx31pdk one. I am not certain whether the CONFIG_SYS_TEXT_BASE should be changed or not: ifdef CONFIG_NAND_SPL CONFIG_SYS_TEXT_BASE = 0x87ec else CONFIG_SYS_TEXT_BASE = 0x87f0 endif I think they are ok - both addresses are valid RAM addresses. The relocation will move then the code at the end of the RAM. And as I understood from i.MX31 manual, the NFC controller does not use the IRAM at all, so the area pointed by your starting stack pointer should not be overwritten. If anyone has any comments/suggestions I will appreciate it. No great idea, really. Probably you need to attach a JTAG debugger and see what happens. Yes, I am setting up a OpenOCD JTAG here to debug this. Thanks, Fabio Estevam ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

Peter, Sorry, since this is my first patch series to U-Boot upstream, I'm still learning the proper etiquette. Let me respond here rather than in the patch comments since there are only 2 unchanged areas WRT comments. 1) IO access functions - I pre-reviewed my patch series with Wolfgang (to hopefully catch any blatant errors and smooth the process) and he indicated that C structs and I/O accessor funcs or macros were preferred to my base+offset original code. Since the ARM is 32-bit, and all of our registers are I/O mapped, it made sense just to cast the necessary HW mem-mapped regs as volatile structs and access the members directly. Works well, is easy to read understand, etc. Let me know (with examples, if possible) how I can make it better. 2) Compiling out support for UARTA or UARTD - didn't seem necessary - size isn't an issue at this point with Tegra2 U-Boot, and some boards (Harmony, for example) are populated w/hardware for both UARTA and UARTD, and can have both on at U-Boot runtime (perhaps for debug out to UARTA whilst normal console I/O goes to UARTD), so I chose to leave the init code for both intact.

Works well, is easy to read understand, etc. Let me know (with examples, if possible) how I can make it better. Both Linux and U-Boot recommend using IO access functions instead pointer accesses, at least in PPC-land, and even for memory mapped registers. I'm not too familiar with ARM, but assume they have the same recommendation. If pointers are used, some CPUs may optimize the access order, thus causing problems. Using IO accessors also ensures that the code is portable. Even if the Tegra doesn't re-order accesses, a driver you write for use in a Tegra could be used on other CPUs that do. eg: http://www.mail-archive.com/u-boot@lists.denx.de/msg18435.html http://lists.denx.de/pipermail/u-boot/2007-December/027595.html It looks like other ARM processors use IO accessors too, eg the recent armada CPU: arch/arm/cpu/arm926ejs/armada100/* A grep of writel in arch/arm shows a number of references. Similarly in the Linux code in arch/arm. ARM maintainers, feel free to chime in if you have comments. 2) Compiling out support for UARTA or UARTD - didn't seem necessary - size isn't an issue at this point with Tegra2 U-Boot, and some boards (Harmony, for example) are populated w/hardware for both UARTA and UARTD, and can have both on at U-Boot runtime (perhaps for debug out to UARTA whilst normal console I/O goes to UARTD), so I chose to leave the init code for both intact. Plus I've never liked code with too many unnecessary ifdef's - makes it less readable, IMO. Yeah, this is grey - I see both sides of the coin. U-Boot generally strives to be as small as possible. You may use a large flash on your eval boards and not care about space, but other system designers may place as small of flash as possible to save cost. It looked like UART_A-UART_E were also going to be supported at some time, which is quite a chunk of code. You also already are defining which serial ports are available at compile time via CONFIG_TEGRA2_ENABLE_UARTA and CONFIG_TEGRA2_ENABLE_UARTD. Anyway, I don't really care much which way you go, just wanted to make sure you were making a conscious decision to not add the ifdefs. I was going to respond to your review w/a direct, inline reply, but I thought it better to get the V2 patch out there before the weekend (we're off for MLK, as well). I'm under some pressure to get a baseline Tegra2 patchset in before the merge window closes. I'll be sure to respond to each issue directly on the list in the future, though.

The only changes I made were to the register access macros to use a couple assembly functions since our EHCI registers require 64-bit addressing and a very quick virtual to physical conversion for the descriptors which is quite fast. Other than that, the code is stock from GIT. Note that we do not use interrupts either but polling. Unless I'm reading it wrong it also looks like in EHCI it only uses one descriptor and I wonder if this might have something to do with it?
