* ARM: UniPhier: enable output of system busMasahiro Yamada2015-01-08-0/+14
| | | | | | | | For NAND boot on PH1-LD4, PH1-sLD8, and some other SoCs, the output of the system bus is disabled by default. It must be enabled by software to have access to the system bus. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
* ARM: UniPhier: fix SRAM size on support cardMasahiro Yamada2015-01-08-3/+3
| | | | | | | | | | The max size of available memories on slot0 and slot1 is 32MB because - EA[25] signal is not output on the save-pin mode which is used PH1-LD4 or later SoCs. - EA[25] signal is not connected by the limitation (or bug?) of the PLD logic of DCC support card.

* arm: omap: reset sata on bootDmitry Lifshitz2015-01-05-0/+9
| | | | | | | | | | | | | 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>

* ARM: bootm: do not add PSCI to fdt when booting in secure mode.Ian Campbell2015-01-05-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
