[U-Boot] [PATCH V2 0/2] bootstage: fix fdt stashing and reporting
by Rommel G Custodio 08 Apr '14

08 Apr '14

In arm, it seems there is a discrepancy in the code. The fdt stashing code uses an undefined variable. In powerpc, implement fdt stashing and pre-boot reporting of bootstage timing data. Fixed a typo in the commit log.

[U-Boot] [PATCH] armv8: Flush dcache before switching to EL2
by York Sun 07 Apr '14

07 Apr '14

For ARMv8, U-boot has been running at EL3 with cache and MMU enabled. Without proper setup for EL2, cache and MMU are both disabled (out of reset). Before switching, we need to flush the dcache to make sure the data is in the main memory.

[U-Boot] [PATCH 0/4] vybrid/tower fixes and enhancements
by stefan＠agner.ch 07 Apr '14

07 Apr '14

From: Stefan Agner <stefan(a)agner.ch> This patch series addresses several fixes and enhancements for the vybrid tower. The patches are originally by Marcel Ziswiler which should remain the Author of the patches, I picked them up since some changes I'm going to submit are building upon them. Changes v3: - Merged patches to reflect one logical change on a pheripherial device level. Changes v2: - Memory offset based reserved ANADIG field naming scheme. - Fixed mux_ctrl_ofs in secondary RMII1 iomux definitions. Marcel Ziswiler (4): arm: vf610: fix anadig register struct arm: vf610: add uart0 clock/iomux definitions arm: vf610: add enet1 support arm: vf610: fix double iomux configuration for vf610twr board arch/arm/include/asm/arch-vf610/crm_regs.h | 57 +++++++++++++++------------ arch/arm/include/asm/arch-vf610/imx-regs.h | 1 + arch/arm/include/asm/arch-vf610/iomux-vf610.h | 12 ++++++ board/freescale/vf610twr/vf610twr.c | 1 - 4 files changed, 45 insertions(+), 26 deletions(-) -- 1.9.0

[U-Boot] Is it OK to use target code from host tools
by Charles Manning 07 Apr '14

07 Apr '14

Hello All I am currently reworking a socfpga signer patch which is part of mkimage. One thing I need to do is to stuff some bytes into a header ensuring the endianism is correct. This is a trivial thing to do in C, but I have been instructed to use the existing functions put_unaligned_le32() etc. These are part of Linux in linux/unaligned/access_ok.h. But this includes <asm/*> It seems to me that this mixing of host space and target space is potentially problematic. Is this a safe thing to do? Thanks Charles

[U-Boot] [PATCH 00/11] arm: add Faraday A36x SoC platform support
by Kuo-Jung Su 07 Apr '14

07 Apr '14

From: Kuo-Jung Su <dantesu(a)faraday-tech.com> These patches introduce Faraday A36x SoC platform support. Here are some public documents for your reference. http://www.faraday-tech.com/html/documentation/index.html There is also a A369 QEMU emulator available at my github account: https://github.com/dantesu1218/qemu.git Here is quick start for QEMU: 1. Download the QEMU source tree $ git clone -b qemu-1.3.0 https://github.com/dantesu1218/qemu.git 2. Build & Install the QEMU: $ ./configure --target-list=arm-softmmu $ make $ make install 3. Launch u-boot with QEMU: $ qemu-system-arm -M a369 -m 512M -nographic -kernel ~/u-boot-2012.10/u-boot Kuo-Jung Su (11): arm: add MMU/d-cache support for Faraday cores net/ftgmac100: add MMU/D-cache support net: add FTMAC110 10/100Mbps ethernet support usb-ehci: add Faraday USB 2.0 EHCI controller support usb-gadget: add FOTG210 USB gadget support i2c: add FTI2C010 I2C controller support spi: add FTSPI010 SPI controller support mtd/nand: add FTNANDC021 NAND flash controller support mtd/spi: add FTSPI020 SPI Flash controller support mmc: add an alternative FTSDC010 driver support arm: add
