Re: [U-Boot] [PATCH v4 1/5] x86: Add a target for running as a coreboot payload

I mean, if this is 'generic', why is there a reference to the chromebook? I think a name like coreboot-x86 could make sense here, but it shouldn't have dependence on drivers specific for chromebook hardware. Only 'generic' drivers as vesa video and keyboard input needs to be referenced on it. Then others developers could extend it to their specific hardware, adding items like ethernet, mmc/sd driver, etc Best Regards, Alan ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

From what I can tell so far, this is not yet well supported in the u-boot mainline. I've been looking at the u-boot-usb branch but its been slow going. Can anyone point me at a particular driver or board that would make a good starting point? What success has there been in using USB attached Ethernet dongles with u-boot?

Hi, This serie of patches was rebased to adds support to iMX31PDK board to boot directly from NAND. Notice these patches don't add support to MTD NAND Flash support to U-Boot (like reading and saving environment parameters in Flash because MTD NAND Flash driver still needs further revision). ___ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot

So, what's the status of this effort? If this your new submission, which still doesn't use nand_spl is not really targeted for upstream merge, I think, it would be better not to mark these mails PATCH. Or have I missed anything? This patch is just a rebase of previous patch, to be merged on u-boot-arm/master repository. I don't have nand_spl working until now. I am new sending patches to u-boot mailing list. So what is the problem when calling it of PATCH? Please, let me know about my mistake, can you explain about it?

[U-Boot] [PATCH 0/3] iMX31: Add iMX31 support to boots from NAND
This serie of patches adds support to iMX31PDK board to boot directly from NAND. Notice these patches don't add support to MTD NAND Flash support to U-Boot (like reading and saving environment parameters in Flash because MTD NAND Flash driver still needs further revision). For people willing to test it follow these simple steps: Create a local copy of u-boot-arm/testing: $ git clone git://git.denx.de/u-boot-arm-next.git u-boot-arm $ cd u-boot-arm $ git checkout -b local_test origin/testing Apply patches: $ patch -p1 ../0001-iMX31-Reducing-start.S-size-to-let-boot-from-NAND.patch $ patch -p1 ../0002-iMX31-Add-support-to-copy-NAND-Flash-code-to-RAM.patch $ patch -p1 ../0003-iMX31-Add-support-to-iMX31PDK-board-and-let-it-boot.patch Set up your cross-compile (we are using one from LTIB): $ export PATH=$PATH:/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/ $ export CROSS_COMPILE=arm-none-linux-gnueabi- Compile U-Boot to iMX31PDK board: $ make mx31pdk_config $ make Flash u-boot.bin to NAND flash (we are using ATK to do that)es doesn't add U-Boot support to erase/write on NAND. These patches will be applied against u-boot-arm/testing, against Magnus Lilja patches. Thanks to Kenneth Johansson about the idea to reduce start.S size.
