[U-Boot] arm: mxs: No arch specific invalidate_icache_all available!
by Stefan Wahren 03 May '17

Hi, i tried to port our Duckbill (based on NXP i.MX28 SoC) to U-Boot v2017.03 [1]. The startup works fine, except of this warning: No arch specific invalidate_icache_all available! I didn't found a MXS specific implementation of invalidate_icache_all(). Did i miss something? Shouldn't be the other MXS boards also affected?

[U-Boot] [PATCH v4 00/35] ARM: i.MX6: SabreSD: Add dts support
by Jagan Teki 03 May '17

03 May '17

This series has full possible dts support for SabreSD DualLite, Quad and Quad Plus and DCD code for DualLite has added in SPL code. The main intention of this series is to add the dts node step by step and remove the legacy code at the end and to make the full functional dts. Preserved non-spl defconfigs, So 3 spl defconfigs and 2 non-spl defconfigs with dtb-enabled. Changes for v4: - rebase on master - Rename imx6[dl|q]_sabresd_spl_defconfig to imx6[dl|q]_sabresd_spl_defconfig - Update README - Move CONFIG_FEC_MXC to configs/mx6[dl|q|qp]sabreauto_defconfigs - Add dts support for non-spl based defconfigs Changes for v3: - rebase on master - Added patch 'ARM: i.MX6: sabresd: Cleanup board code' - Added patch 'ARM: i.MX6DL: sabresd: Move DCD reginit on SPL' Changes for v2: - rebase on master - Added new-patches.

[U-Boot] [PATCH v2 0/5] rockchip: Add a read-only efuse driver for the RK3399 (and derive serial# from fuses on the RK3399-Q7)
by Philipp Tomsich 03 May '17

03 May '17

As the RK3399-Q7 (Puma) differs from our previous modules in how we can force an external boot (on the RK3399-Q7 this holds the eMMC and SPI in reset, until an external signal is removed) through the 'BIOS disable'-signal of the Qseven specification, we can't derive the unique board id reliably from the eMMC's unique id. Instead, for the RK3399-Q7, we rely on the efuse block of the RK3399 and use the (assumed to be unique) cpu_id region. This patch-series adds the required infrastructure and switches the RK3399-Q7 (puma_rk3399) over to this new infrastructure: - adds a rockchip-efuse driver as a misc-device (and permits requests for the clock gate listed in the DTS for the efuse node) - ports the CRC32-based 'serial#' derivation over from Linux - exposes the complete cpu_id field through 'cpuid#' Changes in v2: - added derivation of ethaddr from cpuid Klaus Goger (1): rockchip: board: puma_rk3399: derive ethaddr from cpuid Philipp Tomsich (4): rockchip: clk: rk3399: allow requests for PCLK_EFUSE1024NS rockchip: efuse: add (misc) driver for RK3399 non-secure efuse block rockchip: board: puma_rk3399: add support for serial# and cpuid# via efuses rockchip: defconfig: puma-rk3399: enable RK3399 efuse driver board/theobroma-systems/puma_rk3399/puma-rk3399.c | 117 ++++++++++++++++ configs/puma-rk3399_defconfig | 2 + drivers/clk/rockchip/clk_rk3399.c | 4 + drivers/misc/Kconfig | 14 ++ drivers/misc/Makefile | 1 + drivers/misc/rockchip-efuse.c | 163 ++++++++++++++++++++++ include/configs/puma_rk3399.h | 4 + 7 files changed, 305 insertions(+) create mode 100644 drivers/misc/rockchip-efuse.c -- 1.9.1

[U-Boot] [PATCH 0/5] rockchip: video: rk3399: enable HDMI output
by Philipp Tomsich 03 May '17

03 May '17

This series provides HDMI enablement for the RK3399 and will support video console on the RK3399 either with VOP-lit or VOP-big: - pinctrl and clk support for the hdmi node - a refactoring of rk_vop.c and rk_hdmi.c to allow for the minor differences between the RK3288 and RK3399 VOP and HDMI blocks To see the full series in the context of a working configuration (i.e. including DTS, defconfig, etc. and on top of the MIPI enablement change series from Rockchip), refer to https://git.theobroma-systems.com/puma-u-boot.git/log/?h=puma-hdmi-rfc This has been tested (on top of Eric Gao's change series for MIPI-DSI) using 'bmp display' and 'setenv stdout vidconsole' on the RK3399-Q7 with various HDMI monitors, both for VOP-lit and VOP-big (setting the other one to 'disabled').
