[U-Boot] [PATCH V2 1/7] ARM: tegra: rename dummy XUSB padctl implementation
by Stephen Warren 29 Oct '15

29 Oct '15

From: Stephen Warren <swarren(a)nvidia.com> A future patch will soon move some of the XUSB padctl code into a common file in arch/arm/mach-tegra. Rename the existing dummy XUSB padctl file to avoid conflicting with that, or being confusing.

[U-Boot] [PATCH 3/3][v4] crypto/fsl: SEC driver cleanup for 64 bit and endianness
by Aneesh Bansal 29 Oct '15

29 Oct '15

The SEC driver code has been cleaned up to work for 64 bit physical addresses and systems where endianess of SEC block is different from the Core. Changes: 1. Descriptor created on Core is modified as per SEC block endianness before the job is submitted. 2. The read/write of physical addresses to Job Rings will be depend on endianness of SEC block as 32 bit low and high part of the 64 bit address will vary. 3. The 32 bit low and high part of the 64 bit address in descriptor will vary depending on endianness of SEC.

Correct the black screen console of the HDMI output (Thanks to Aka) Correct an missing allocated video struct: When use a bitmap function or splash screen u-boot stop to work correctly: The panel_info.cmap is not allocated and has a NULL value. The cmap is fill at 0x000000 and all the first sector (device tree include because it’s at 0x100) is overwritten. Patch is test on the last stable branch master. Best regards

Changes in v2: 1./ re-order SAMA5D2 statements alphabetically. 2./ remove redundant "Unknown CPU type". 3./ rework sama5d2's macros. 4./ remove some #ifdef before functions. 5./ move CONFIG_CMD_SF to Kconfig. 6./ remove NAND macros from config file. 7./ CONFIG_BOOTCOMMAND for sf uses defines in at91-sama5_common.h. arch/arm/mach-at91/Kconfig | 5 + arch/arm/mach-at91/armv7/Makefile | 1 +
