* sun6i: Make dram clk and zq value Kconfig optionsHans de Goede2015-01-14-7/+5
| | | | | | | | | | | | It turns out that there is a too large spread between boards to handle this with a default value, turn this into Kconfig options, and set the values the factory images are using for the Colombus and Mele_M9 boards. Note this changes the ZQ default when not overriden through defconfig from 120 to 123, as that is what most boards seem to actually use.

* ARM: UniPhier: add UART initialization routine for low-level debugMasahiro Yamada2015-01-08-0/+104
| | | | | | | | | | | The low-level debugging functions are useful to debug the early boot stage where the full UART driver is not available. UniPhier SoCs need to initialize the UART port 0 to use this feature. The initialization routine is called at the very entry of the lowlevel_init().

| | | | | | | | | | | | | 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.

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current current watchdog timeout of 12 seconds is a bit small for booting into Linux, especially when using a NFS based rootfs. So lets change this timeout to a more defensive value of 30 seconds. Also we now call the hw_watchdog_init() function so that we override the value already configured from the Preloader.
