2018-07-03arm: timer: sunxi: add Allwinner timer erratum workaroundAndre Przywara
The Allwinner A64 SoCs suffers from an arch timer implementation erratum, where sometimes the lower 11 bits of the counter value erroneously become all 0's or all 1's [1]. This leads to sudden jumps, both forwards and backwards, with the latter one often showing weird behaviour. Port the workaround proposed for Linux to U-Boot and activate it for all A64 boards. This fixes crashes when accessing MMC devices (SD cards), caused by a recent change to actually use the counter value for timeout checks. Fixes: 5ff8e54888e4d26a352453564f7f599d29696dc9 ("sunxi: improve throughput in the sunxi_mmc driver") [1] http://lists.infradead.org/pipermail/linux-arm-kernel/2018-May/576886.html Signed-off-by: Andre Przywara <andre.przywara@arm.com> Reviewed-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Jagan Teki <jagan@amarulasolutions.com> Tested-by: Andreas Färber <afaerber@suse.de> Tested-by: Guillaume Gardet <guillaume.gardet@free.fr>
2018-07-03arm: timer: factor out FSL arch timer erratum workaroundAndre Przywara
At the moment we have the workaround for the Freescale arch timer erratum A-008585 merged into the generic timer_read_counter() routine. Split those two up, so that we can add other errata workaround more easily. Also add an explaining comment on the way.

2018-06-29ARM: Introduce ability to enable invalidate of BTB with ICIALLU on ↵Nishanth Menon
Cortex-A15 for CVE-2017-5715 As recommended by Arm in [1], ACTLR[0] (Enable invalidates of BTB) needs to be set[2] for BTB to be invalidated on ICIALLU. This needs to be done unconditionally for Cortex-A15 processors. Provide a config option for platforms to enable this option based on impact analysis for products. NOTE: This patch in itself is NOT the final solution, this requires: a) Implementation of v7_arch_cp15_set_acr on SoCs which may not provide direct access to ACR register. b) Operating Systems such as Linux to provide adequate workaround in the right locations. c) This workaround applies to only the boot processor. It is important to apply workaround as necessary (context-save-restore) around low power context loss OR additional processors as necessary in either firmware support OR elsewhere in OS.

2018-06-29usb: sunxi: Use proper reg_mask for clock gate, resetJagan Teki
Masking clock gate, reset register bits based on the probed controller is proper only due to the assumption that masking should start with 0 even thought the controller has separate PHY or shared between OTG. unfortunately these are fixed due to lack of separate clock, reset drivers. Say for example EHCI1 - EHCI3 in the datasheet (EHCI0 is for the OTG) so we need to start reg_mask 0 - 2. This patch calculated the mask, based on the register base so that we can get the proper bits to set with respect to probed controller. We even do this masking by using PHY index specifier from dt, but dev_read_addr_size is failing for 64-bit boards. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

fdt_file is looking for imx6ul-geam-kit.dtb but Linux has imx6ul-geam.dtb, since Linux skipped -kit on file name by below commit. "ARM: dts: imx6ul-geam: Skip suffix -kit from dts name" (sha1: 182de5ebce71e469cfa686fcdf08c9cbe11ece97) So, due to this mismatch U-Boot failed to pick the proper dtb which eventually break the Linux boot.

Add option to the booti_setup() which indicates to it that the caller requires the image to be relocated to the beginning of the RAM and that the information whether the image can be located anywhere in RAM at 2 MiB aligned boundary or not is to be ignored. This is useful ie. in case the Image is wrapped in another envelope, ie. fitImage and not relocating it but moving it would corrupt the envelope.
