| | | | | | | | | | | | | | | | | | | | Add a Kconfig option to disable the Integrated Graphics Device (IGD) so that it does not show in the PCI configuration space as a VGA disaplay controller. This gives a chance for U-Boot to run PCI/PCIe based graphics card's VGA BIOS and use that for the graphics console.

| * | arm: mvebu: Add DM (driver model) supportStefan Roese2015-10-21-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds driver model support for some Marvell MVEBU SoC's. Including Armada XP and 38x. All 3 currently mainlined boards are converted. DM is now selected automatically for MVEBU platforms. With this DM support now available for MVEBU, hardcoding the base addresses and other information is not necessary any more. Probing should be done by using the values provided via the device tree now instead. For this the driver also need to be converted to DM. Patches for some of the drivers will follow.

This will make the code continue executing in crt0.S _main(), from which the board_init_r() is called.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now have generic q8_a?3_defconfig files for Q8 formfactor tablets with an A13 / A23 / A33 SoC, there is no need for these PCB variant specific defconfig-s and they only serve to confuse the user. Note that in case of the forfun_q88db_defconfig and TZX-Q8-713B7_defconfig for A13 based Q8 tablets there is not even a dts file for these in the upstream kernel, which is all the more reason to remove them. The generic q8_a?3_defconfig files have been tested on an Et_q8_v1_6, Ippo_q8h_v1_2_a33_1024x600, Ippo_q8h_v1_2 and TZX-Q8-713B7 tablet, and the forfun_q88db_defconfig is identical to q8_a13_tablet_defconfig. This leaves only the Ippo_q8h_v5 untested with the new generic defconfigs but there is no reason to assume that it will not work.

Enabling D and I prefetch bits helps improve SDRAM performance on the platform. Also, we need to enable bit 22 of the L2. By not having bit 22 set in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 623d96e89aca6("imx: wdog: correct wcr register settings") issuing a 'reset' command causes the system to hang. Unlike i.MX and Vybrid, the watchdog controller on LS102x is big-endian. This means that the watchdog on LS1021 has been working by accident as it does not use the big-endian accessors in drivers/watchdog/imx_watchdog.c. Commit 623d96e89aca6("imx: wdog: correct wcr register settings") only revelead the endianness problem on LS102x. In order to fix the reset hang, introduce a reset_cpu() implementation that is specific for ls102x, which accesses the watchdog WCR register in big-endian format. All that is required to reset LS102x is to clear the SRS bit. This approach is a temporary workaround to avoid a regression for LS102x in the 2015.10 release. The proper fix is to make the watchdog driver endian-aware, so that it can work for i.MX, Vybrid and LS102x.

However when upgrading to a Debian Jessie we started seeing frequent segmentation faults from gcc when building the kernel, to the extent that it is unable to successfully build the kernel twice in a row, and often fails on the first attempt. Searching around I found https://bugs.launchpad.net/arndale/+bug/1081417 which pointed towards http://www.spinics.net/lists/kvm-arm/msg03723.html and CPU Errata 773022 and 774769. This errata needs to be applied to all processors in an SMP system, meaning that the usual strategy of applying them in arch/arm/cpu/armv7/start.S is not appropriate (since that applies to the boot processor only). Instead we apply these errata in the secure monitor which is code that is traversed by all processors as they are brought up. The net affect on Arndale is that ACTLR changes from 0x40 to 0x2000042. I ran 17 kernel compile iterations overnight with no segfaults. Runtime testing was done on our v2014.10 based branch and forward ported (with only minimal and trivial contextual conflicts) to current master, where it has been build tested only. I suppose in theory these errata apply to any Exynos5250 based boards, but Arndale is the only one I have access to and I have therefore chosen to be conservative and only apply it there. Also, reorder CONFIG_ARM_ERRATA_794072 in README to make the list numerically sorted. Signed-off-by: Ian Campbell <ian.campbell@citrix.com>

* | | rockchip: Reconfigure the malloc based to point to system memorySjoerd Simons2015-10-03-0/+7
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When malloc_base initially gets setup in the SPL it is based on the current (early) stack pointer, which for rockchip is pointing into SRAM. This means simple memory allocations happen in SRAM space, which is somewhat unfortunate. Specifically a bounce buffer for the mmc allocated in SRAM space seems to cause the mmc engine to stall/fail causing timeouts and a failure to load the main u-boot image. To resolve this, reconfigure the malloc_base to start at the relocated stack pointer after DRAM has been setup. For reference, things did work fine on rockchip before 596380db was merged to fix memalign_simple due to a combination of rockchip SDRAM starting at address 0 and the dw_mmc driver not checking errors from bounce_buffer_start. As a result, when a bounce buffer needed to be allocated mem_align simple would fail and return NULL. The mmc driver ignored the error and happily continued with the bounce buffer address being set to 0, which just happened to work fine..

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This device uses SDHCI driver, for eMMC and SD cards. Trying bind the DW MMC driver with fdt node without all required properties, causes printing an error. This commit disables the DW MMC node.
