[U-Boot] [PATCH v2 0/4] Enable the host controller and hub on PopMetal board
by Kever Yang 03 Dec '16

03 Dec '16

The PopMetal board based on rk3288 SoC have 3 USB 2.0 host ports from a usb 2.0 hub which connect to the rk3288 usb host1. This patch set enable those ports by enable the rk3288 usb host controller driver and usb host function like storage and ether, enable the port power and de-assert the hub reset signal. Test with U-disk on Popmetal board. => usb start starting USB...

With CONFIG_ROCKCHIP_SPL_BACK_TO_BROM enabled, the environment is inside u-boot. So solve it by moving environment after u-boot.

[U-Boot] Please assign custodian for: u-boot-pmic / maintainers for: Samsung boards
by Przemyslaw Marczak 03 Dec '16

03 Dec '16

Hello, During the last year I was assigned to an internal project, and I haven't time for an Open Source activity, so I was quite inactive on U-Boot list. I finish work today at Samsung, so my e-mail address will become inactive. My new work is not related with Open Source activity. I was maintaining three boards: ./board/samsung/smdk5420/MAINTAINERS ./board/samsung/universal_c210/MAINTAINERS ./board/samsung/odroid/MAINTAINERS Lukasz Majewski will maintain Odroid-XU3 (smdk5420), Lukasz please send the patch with this change. Yaehoon, I thing that you are the right person for the C210/Odroid U3 boards, since you put a lot of work in Samsung's boards code at all. I also had PMIC tree in U-Boot, but I haven't time to maintain it. Simon, you put a big effort into PMIC framework, and also last year, you reviewed a lot of code for PMIC drivers. Are you interested to take the PMIC tree as one of your working sub-tree? Tom, if Simon accept this proposition, then can you please remove the PMIC tree from the git server? Thank you all for cooperation! Best regards, -- Przemyslaw Marczak Samsung R&D Institute Poland Samsung Electronics p.marczak(a)samsung.com

[U-Boot] [PATCH 00/24] sunxi: Allwinner A64: SPL support
by Andre Przywara 03 Dec '16

03 Dec '16

Hi, this series introduces SPL support for the Allwinner A64 SoC. In contrast to the previous RFC this one includes support for both AArch64 and AArch32 SPL builds. Still the FIT support is missing, which means the functionality is limited. Due to the missing ARM Trusted Firmware (ATF) in this firmware chain one loses Ethernet and SMP, among other minor things. I will send the FIT support later on top of this. The first two patches are fixes that I sent out before, not sure if they landed somewhere already. Patch 2-8 prepare the SPL code to be compiled for 64-bit in general and AArch64 in particular. Patch 9-11 refactor the existing boot0 header functionality to be used by patch 12, which introduces the 64-bit switch in the first SPL instructions. Patches 13-18 then introduce the actual core of the SPL support: the DRAM initialization, courtesy of Jens. This piggy backs on the existing H3 DRAM code, deviating where needed. Patch 19 finally enables the 64-bit SPL support. So now building the existing pine64_plus_defconfig will generate a sunxi-spl.bin, which can be prepended to the U-Boot proper image (not .bin) to boot from an SD card. Due to the missing ATF support this is of limited usability at the moment, though. Also FEL support requires more love - to switch back to AArch32 before returning to FEL (without crashing, that is ;-), so this is disabled. On my setup this results in a 26KB SPL binary, which is close to the 28K limit mksunxiboot imposes at the moment. Adding anything (like FIT support or DEBUG) will exceed this, and although I have patches to let mksunxiboot get close to 32KB, this is the ulimate frontier. So patches 20-23 then teach the SPL how to detect an U-Boot image file of a different bitness and do the RMR switch from AArch32 to AArch64, if needed. This is used by the final patch 24, which creates another _defconfig to let the SPL compile for AArch32 using the Thumb2 encoding. This results in a binary of less than 17KB in my case, so has plenty of room for extensions. I know this is nasty stuff, so I appreciate any comments. Cheers, Andre.

[U-Boot] [PATCH] Fix zynq returning a wrong retval in read_rom_hwaddr
by Olliver Schinagl 02 Dec '16

As described in the commit, I think because the return value is never checked, it just worked. I cleaned it up a bit so should at least return the intended value.

[U-Boot] T2080 l2-cache-controller compatible string overwritten by ft_fixup_l2cache
by Chris Packham 01 Dec '16

01 Dec '16

Hi, I was just looking at what it would take to add the T2080 L2 cache to the mpc85xx_edac driver in Linux. At a cursory glance all the registers appear to be there so I figured I'd just add the appropriate entry to the of match table. To my surprise I found that the compatible string in my device tree was overwritten with "cache". I've tracked this down to the CONFIG_SYS_FSL_QORIQ_CHASSIS2 implementation of ft_fixup_l2cache in u-boot. The CONFIG_L2_CACHE version seems to take care to update the device tree node to compatible = "fsl,t2080-l2-cache-controller", "cache"; but the CONFIG_SYS_FSL_QORIQ_CHASSIS2 version just sets this to compatible = "cache"; Is this an over-site or is it intentional? Thanks, Chris
