11c08d4ec5 mx5: Define a common get_board_rev()
When booting a FSL kernel based on 2.6.35 it is necessary to pass the revision

492938a334 nitrogen6x: Setup CCM_CCOSR register
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."

8870e45996 imx: Move some i.MX common functions into the imx-common directory
This patch moves the following functions into the imx-common
directory:

- mxs_wait_mask_set()
- mxs_wait_mask_clr()
- mxs_reset_block()

These are currently used by i.MX28. But the upcoming GPMI NAND port

TEGRA_SOC_T25, TEGRA_SOC_T33, etc.

3ebbbfe4c7 Tegra: Restore cp15 VBAR _start vector write for ARMv7
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.

eb222d1d7d ARM: tegra: support T33 SKU of Tegra30
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.

c4a4e2e20c ARMv7: start.S: stay in HYP mode if u-boot is entered in it
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.

0f1411bc8d spi: mxc_spi: Set master mode for all channels
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.
