Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no additional instructions were emitted related to this patch. Booted an image on a MPC8541 based board successfully. Signed-off-by: Curt Brune c...@cumulusnetworks.com --- drivers/ddr/fsl/ctrl_regs.c | 10 +- 1 file changed

[U-Boot] MPC8541 / MPC8555E: DDR_SDRAM_CLK_CNLT[SS_EN] handling

2015-02-12 Thread Curt Brune
Hello, I am curious about the setting of the SS_EN bit in the DDR_SDRAM_CLK_CNLT register: Source synchronous enable. This bit field must be set during initialization. See Section 9.6.1, “DDR SDRAM Initialization Sequence,” for details. 0 - Reserved 1 - The address and command

Re: [U-Boot] U-Boot Regression Testing

2013-10-10 Thread Curt Brune
- Original Message - Have a look at DUTS [1]; the test cases implemented there serve a double purpose: 1) they help testing (some of) the functionality of U-Boot (and Linux) on a specific board, and 2) they generate the needed include files to produce a board-specific version of the

[U-Boot] U-Boot Regression Testing

2013-10-09 Thread Curt Brune
Hello, I have some questions about how U-Boot regression testing works. I am assuming some regression testing happens during the release period across some representative sample of boards and architectures. I know people check for compilation failures with MAKEALL, but I am wondering about

[U-Boot] representing multi-socket CPU platform in .dts

2013-05-08 Thread Curt Brune
Hi, What does u-boot expect to find in the device tree for a system with multiple CPU sockets (not multi-core, but multiple physical CPUs) ? For example if you have a two socket system, with a dual-core CPU per socket would there just be 4 nodes in cpus {} with reg = 0, 1, 2, 3 or is there

[U-Boot] USB Device Identification -- non-removable USB NAND flash

2013-04-17 Thread Curt Brune
Hi - Looking for suggestions on how to identify a particular USB mass storage device on my platform. My platform has a P2020 SoC. The SoC USB controller is connected to an on board USB hub. The hub has 3 connections as follows: +-+ | |---[USB flash controller, fronting a

[U-Boot] dtb vs. kernel command line arguments

2013-03-04 Thread Curt Brune
Hello - I want to pass a number of arguments from u-boot to the booted kernel. The arguments are needed by user space applications, not the kernel. I can think of two ways: 1. append args by setting bootargs. 2. add nodes to the dtb before booting. Is there a preferred way to pass

Hello, I am following up on this thread: Merging device trees at runtime for module-based systems http://lists.denx.de/pipermail/u-boot/2012-November/139618.html I do not have a modular based system, so I do not need the full flexibility of merging DT fragments at runtime. However, I am very
