[U-Boot] [PATCH v4 0/5] Add a coreboot board, CPU, and configuration, and target.
by Gabe Black 17 Nov '11

17 Nov '11

This series of changes adds a coreboot board, CPU, configuration, and build target. These patches are all needed in order to get to a buildable state and could potentially be merged together into larger changes. Merging them all would create a change that, in my opion, is a bit too big, so I'll leave it to the reviewers to decide which patches should be merged. Changes in v2: Change capitalization of the x86 tag. Get rid of some dead/unnecessary code in the Makefile and coreboot.c. Changes in v3: Move the Signed-off-by line up. Change the summary line tag style. Changes in v4: Change the summary tag style. Gabe Black (5): x86: Add a target for running as a coreboot payload x86: Add a basic implementation for a coreboot board x86: Add a preliminary coreboot configuration header x86: Add an implementation for a coreboot CPU x86: Make the serial port work for the coreboot board arch/x86/cpu/coreboot/Makefile | 55 ++++++ arch/x86/cpu/coreboot/asm-offsets.c | 25 +++ arch/x86/cpu/coreboot/coreboot_car.S | 29 +++ arch/x86/cpu/coreboot/sdram.c | 39 ++++ board/chromebook-x86/coreboot/Makefile | 53 +++++ board/chromebook-x86/coreboot/coreboot.c | 77 ++++++++ board/chromebook-x86/coreboot/coreboot_pci.c | 30 +++ board/chromebook-x86/coreboot/coreboot_start.S | 29 +++ board/chromebook-x86/coreboot/coreboot_start16.S | 46 +++++ boards.cfg | 1 + include/configs/coreboot.h | 225 ++++++++++++++++++++++ include/serial.h | 2 +- 12 files changed, 610 insertions(+), 1 deletions(-) create mode 100644 arch/x86/cpu/coreboot/Makefile create mode 100644 arch/x86/cpu/coreboot/asm-offsets.c create mode 100644 arch/x86/cpu/coreboot/coreboot_car.S create mode 100644 arch/x86/cpu/coreboot/sdram.c create mode 100644 board/chromebook-x86/coreboot/Makefile create mode 100644 board/chromebook-x86/coreboot/coreboot.c create mode 100644 board/chromebook-x86/coreboot/coreboot_pci.c create mode 100644 board/chromebook-x86/coreboot/coreboot_start.S create mode 100644 board/chromebook-x86/coreboot/coreboot_start16.S create mode 100644 include/configs/coreboot.h -- 1.7.3.1

[U-Boot] Application of patch submitted during the previous Merge Window
by Graeme Russ 17 Nov '11

17 Nov '11

Hi Wolfgang, With the next release pending and the next Merge Window about to open, I thought I might take the opportunity to ask a question that's been on my mind...What is the 'procedure' (for want of a better word) you use for patches applied during the merge window? Now I know maintainers typically keep a 'next' branch which they can quickly rebase and issue a pull request for, but you don't seem to keep such a branch for the 'generic' patches (well, there is one, but it is now nine months old) Just wondering how we should be tracking said patches - Do you want us to ping you when the Merge Window opens, or do you have them nicely piled up in Patchwork ready to apply? Personnaly, I like the idea of the next branch more than Patchwork, just to be consistent with the maintainers Regards, Graeme

[U-Boot] Question about baud rate
by djantzen 17 Nov '11

17 Nov '11

Hi, I'm using a board similar to canyonlands with a ppc460ex. The baud rate for ttyS0 is set to 115200 by the console= bootarg, but I'd also like to set ttyS1-3 to 115200 also. For each of the three uarts, the device tree has the following line: current-speed = <0>; /* Filled in by U-Boot */ How do I go about configuring u-boot to fill these with the baud rate I choose? Sorry for the silly question! Thanks, Dan

[U-Boot] [PATCH] env: allow to export only selected variables
by Wolfgang Denk 17 Nov '11

17 Nov '11

New syntax: env export [-t | -b | -c] [-s size] addr [var ...] With this change it is possible to provide a list of variables names that shall be exported. Whenno arguments are given, the whole environment gets exported. NOTE: The new handling of the "size" argument means a change to the user API.

[U-Boot] SSBI driver
by hanumant 17 Nov '11

17 Nov '11

Hi I am trying to implement a SSBI driver for a board. . The driver is meant to be portable to multiple boards by the same vendor. Keeping this in mind 1)Would drivers/misc/ be the right location to implement this driver? 2)If not can I make a ($vendor)-common in the cpu directory to implement the driver given that the driver is going to be applicable for multiple socs by the same vendor. ie have something like the below. have arch/arm/cpu/armv7/($vendor)-common & arch/arm/cpu/armv7/($SOC). I believe there is already precedent for this? Any input is appreciated. Thanks Hanumant
