* nitrogen6x: Setup CCM_CCOSR registerFabio Estevam2013-04-251-0/+1
| | | | | | | | | | | | CKO1 drives sgtl5000 codec clock on nitrogen boards and wandboard. Doing this setup in the bootloader will allow us to remove a lot of code in arch/arm/mach-imx/mach-imx6q.c from the mainline kernel. Also, according to Eric Nelson: "enabling the clock <in the bootloader> will remove squeal after an ungraceful reboot (watchdog) if hooked up to speakers."

* | Tegra: Restore cp15 VBAR _start vector write for ARMv7Tom Warren2013-04-151-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53), and caused the old monilithic Tegra builds to hang due to an undefined instruction trap. Previously, the code needed to run on both the AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register. I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but now that we use SPL, and boot the AVP w/o any ARMv7 code, I can revert my change, and make Aneesh's change apply to Tegra.

* | ARM: tegra: support T33 SKU of Tegra30Stephen Warren2013-04-152-0/+2
|/ | | | | | | | | | | | | | | | | | | Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically to any other Tegra30. An alternative would be to simply remove the SKU checking from tegra_get_chip_type(); most use of the value most likely simply wants to know the current chip, not the specific SKU. Or, the function could be split into separate tegra_get_chip() and tegra_get_sku() for the cases where differentiation really is required. I wonder whether tegra_get_chip_type() should printf() whenever any unkown chip/SKU is found, although perhaps the function is called so early that the printf() wouldn't actually make it to the UART anyway.

| | | | | | | | | | The KVM and Xen hypervisors for the Cortex-A15 virtualization implementation need to be entered in HYP mode. Should the primary board firmware already enter HYP mode (Calxeda firmware does that), we should not deliberately drop back to SVC mode. Since U-boot does not use the MMU, running in HYP mode is just fine. Signed-off-by: Andre Przywara <andre.przywara@linaro.org>

Rewrite the ASSERT() in arch/arm/cpu/u-boot-spl.lds to separately test image (text,data,rodata...) size, BSS size, and full footprint each against its own max, and make Tegra boards check full footprint.

| * spi: mxc_spi: Set master mode for all channelsFabio Estevam2013-04-132-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi clock glitch durant reset) solved, is back now and itwas re-introduced by commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling). Actually the glitch is happening due to always toggling between slave mode and master mode by configuring the CHANNEL_MODE bits in this reset function. Since the spi driver only supports master mode, set the mode for all channels always to master mode in order to have a stable, "glitch-free" SPI clock line.
