[U-Boot] [PATCH 1/2] dfu:ext4:fix Fix ext4{read|write} command formatting
by Lukasz Majewski 08 Jul '13

08 Jul '13

In the following commit: "dfu: Support larger than memory transfers." SHA1: ea2453d56b8860dbd18a3c517531ffc8dcb5c839 The ext4{read|write} command formatting has been changed. It removed a write mandatory [sizebytes] parameter. It extents DFU_FS_EXT4 case at mmc_file_op to provide mandatory parameter for DFU write.

[U-Boot] [PATCH] arm:trats: Increase malloc pool size (for DFU ext4 transfers)

Commit: dfu: make data buffer size configurable SHA1: 89a72b2e0e141042c9109185e02d39b2107ffc62 replaced statically allocated buffers with one allocated with memalign.

[U-Boot] [PATCH v2 0/7] ARMv7: Add HYP mode switching support
by Andre Przywara 04 Jul '13

04 Jul '13

(for GIT URL and Changelog see below) ARM CPUs with the virtualization extension have a new mode called HYP mode, which allows hypervisors to safely control and monitor guests. The current hypervisor implementations (KVM and Xen) require the kernel to be entered in that HYP mode. This patch series introduces a configuration variable CONFIG_ARMV7_VIRT which enables code to switch all cores into HYP mode. This is done automatically during execution of the bootm command. The process of switching into HYP mode requires the CPU to be in secure state initially when entering u-boot, it will then setup some register and switch to non-secure state. This requires the GIC to be programmed properly first. Explanations about the details are in the commit messages of the respective patches. The patches are structured like this: 1/7: prepare header file 2/7: add monitor handler (assembly) 3/7: add per CPU non-secure switch routine (assembly) 4/7: add system wide non-secure setup and link to bootm command (C) 5/7: add SMP functionality 6/7: add HYP mode switching 7/7: enable code on Versatile Express TC2 So up to patch 5/7 this code should work on non-virtualization capable CPUs also. The code aims to be as generic as possible, though currently it has only been tested on the Versatile Express TC-2 board. The last patch thus enables the feature for that board. For convenience there is a GIT tree which you can pull these patches from ("hypmode_v2" branch): git://git.linaro.org/people/aprzywara/u-boot.git Changes RFC..v1 * not a dedicated command anymore, code run by bootm & friends * protecting code with #ifdefs to avoid unnecessary inclusion and accidental crashing (when accessing restricted registers) * moving prototypes to header file to meet checkpatch recommendation * adding comment as proposed by Christoffer Changes v1..v2 mostly style and code layout changes * restructure assembly code to live in a new file and not start.S * split smp, nonsec_init and hyp_init to be separate functions * used named constants from common header files * split C function to be more readable * extend comments to be more precise and elaborate * add provision to override GIC base address (needed for Arndale?) * add configuration variable to enable VExpress specific SMP code * use writel/readl for MMIO GIC accesses * remove superfluous isb instructions * more minor fixes Please review and comment! I am pretty sure I missed some of the comments from the earlier series, so if you find something that was mentioned before, feel free to repeat it. Contributions and comments to support other boards are welcome.

[U-Boot] [PATCH v2 0/2] SPI flash update command
by Gerlando Falauto 03 Jul '13

03 Jul '13

Hi, this patchset allows "sf update" to erase+write a number of bytes which is not a multiple of the sector size. Start address must still be sector-aligned though. The first patch trivially makes it such it will always erase an entire sector before writing, regardless of the amount of data to write (i.e. the last sector is erased completely before writing it only partially). The second patch just makes sure that the original data at the end of the sector is written back so to apparently remain unchanged. Changes from v1 [April, 03, 2012 (!)]: - Rebased on top of u-boot-spi/master Gerlando Falauto (2): cmd_sf: let "sf update" erase last sector as a whole cmd_sf: "sf update" preserve the final part of the last sector common/cmd_sf.c | 18 ++++++++++++++++-- 1 file changed, 16 insertions(+), 2 deletions(-) -- 1.7.10.1
