2015-01-05arm: omap: reset sata on bootDmitry Lifshitz
On OMAP platforms (like OMAP5) Linux kernel fails to detect a SATA device if it is used by U-Boot. It happens because U-Boot does not reset SATA controller before boot. Reset the controller on OS boot so that Linux will have a clean state to work with. Signed-off-by: Dmitry Lifshitz <lifshitz@compulab.co.il> Reviewed-by: Tom Rini <trini@ti.com>

2015-01-05ARM: bootm: do not add PSCI to fdt when booting in secure mode.Ian Campbell
Commit 8bc347e2ec17 "ARM: bootm: Allow booting in secure mode on hyp capable systems" added the capability to select nonsec vs sec mode boot via an environment var. There is a subtle gotcha with this functionality, which is that the PSCI nodes are still created in the fdt (via armv7_update_dt->fdt_psci) even when booting in secure mode. Which means that if the kernel is PSCI aware then it will fail to boot because it will try and do PSCI from secure world, which won't work. This likely didn't get noticed before because the original purpose was to support booting the legacy linux-sunxi kernels which don't understand PSCI. To fix expose boot_nonsec (renaming with armv7_ prefix) outside of bootm.c and use from the virt-dt code. As well as avoiding the creation of the PSCI nodes we should also avoid reserving the secure RAM, so do so.

This controller was introduced on Tegra114 to handle XUSB pads. On Tegra124 it is also used for PCIe and SATA pin muxing and PHY control. Only the Tegra124 PCIe and SATA functionality is currently implemented, with weak symbols on Tegra114. Tegra20 and Tegra30 also provide weak symbols for these functions so that drivers can use the same API irrespective of which SoC they're being built for.

Nyan-big is a Tegra124 clamshell board that is very similar to venice2, but it has a different panel, the sdcard cd and wp sense are flipped, and it has a different revision of the AS3722 PMIC. This is the Acer Chromebook 13 CB5-311-T7NN (13.3-inch HD, NVIDIA Tegra K1, 2GB). The display is not currently supported, so it should boot on other nyan-based Chromebooks also, but only the device tree for nyan-big is provided here.

2014-12-09ARM: UniPhier: detect the number of flash banks at run-timeMasahiro Yamada
Some UniPhier boards are equipped with an expansion slot that some optional SRAM/NOR-flash cards can be attached to. So, run-time detection of the number of flash banks would be more user-friendly. Until this commit, UniPhier boards have achieved this by (ab)using board_flash_wp_on() because the boot failed if flash_size got zero. Fortunately, this problem was solved by commit 70879a92561a (flash: do not fail even if flash_size is zero). Now it is possible to throw away such a tricky workaround. This commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further refactoring. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
