To prevent the confusion, use the get_mmc_clk() instead of mmc_clk().
get_mmc_clk() is more exactly name.

Dear Mateusz Zalega,
This commit unifies board-specific USB initialization implementations
under one symbol (usb_board_init), declaration of which is available in
usb.h.
New API allows selective initialization of USB controllers whenever needed.

Hi there,
I want to chose from two different Android kernel images to be booted
during SPL execution. Thus, I guess I need to a) pass u-boot.img two
different parameters or b) call two different u-boot.img files, which in
turn call the corresponding kernel images?
Thanks in advance,

The lower 5 bit of MVBAR is UNK/SBZP.
So, Monitor Vector Base Address must be 32-byte aligned.
On the other hand, the secure monitor handler does not need
32-byte alignment.

This patch series add support for TI qspi controller and in the process also
add support for quad read and memory mapped read
in mtd spi framework.
Testing details:
Did a boot from qspi mode on DRA7xx.
Testing details present in the last patch of
the series.
Currently, TI qpsi controller
Qspi controller can have a memory mapped port which can be used for
data read. Added support to enable memory mapped port read.
This patch enables the following:
- It enables exchange of memory map address between mtd and qspi
through the introduction of memory_map flag.
- Add support to
Clock requirement for qspi clk is 192 Mhz.
According to the below formulae,
f dpll = f ref * 2 * m /(n + 1)
clockoutx2_Hmn = f dpll / (hmn+ 1)
fref = 20 Mhz, m = 96, n = 4 gives f dpll = 768 Mhz
For clockoutx2_Hmn to be 768, hmn + 1 should be 4.
