On (at least) OMAP4, the USB DPLL is required to be setup for the internal PHY

The Amazon Kindle Fire (first generation) codename kc1 is a tablet that was

I2C is often enabled withing the U-Boot SPL, thus those clocks are required to

There is no distinction between essential and non-essential mux configuration,

Boards using the TWL6030 regulator may not all use the LDOs the same way.
Some might also not use MMC1 at all, so VMMC would't have to be enabled.
This delegates TWL6030 MMC power initializations to board-specific functions,
that may still call twl6030_power_mmc_init for the default behavior.

Not every device has multiple MMC slots available, so it makes sense to enable
only the required LDOs for the available slots. Generic code in omap_hsmmc will
enable both VMMC and VAUX1, in doubt.

This enables the VAUX1 supply, used for eMMC power in standard configurations.
Its voltage is determined by the value of the BOOT2 pin of the TWL6030.
Note that the TWL6030 might already have enabled this regulator at startup
(depending on the value of the BOOT3 pin of the TWL6030), according to the
TWL6030 datasheet.

Reboot mode garbage is found on cold reset and might be seen as valid on the

There is no need to set the reboot mode to a particular value prior to reboot,
since valid values will have been caught and cleared earlier.
In addition, this breaks the reboot-bootloader fastboot call, by overriding the

Global definition of priv seems no-sense to use it
for non-dm case and pass the pointer to functions
which are common to both dm and non-dm.
So, fix this by removing omap3_spi_slave from non-dm
and make visible to omap3_spi_priv for both dm and non-dm.

this should also help 'future-proof' in the event the structure changes.

Commit (20fae0a - ARM: DRA7: DDR: Enable SR in Power Management Control)
enables Self refresh mode by default and during warm reset the EMIF
contents are preserved. After warm reset EMIF sees that it is idle and
puts DDR in self-refresh. When in SR, leveling operations cannot be done
as DDR can only accept SR exit command, so its hanging during warm reset.
In order to fix this reset the power management control register before
EMIF initialization if it is a warm reset.

Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.
This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.
For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h
