In order to completely halt the AVP processor, we should simply write
FLOW_MODE_STOP without any extra options that allow wakeup. Amend the
code to do this.
I believe that enabling FIQ_1 and IRQ_1 allow the CPU to be awoken by
interrupts. We don't want this; if later SW wishes to use the AVP, it
should be reset and booted from scratch.
Related, the bits that were previously IRQ_1 and FIQ_1 have a slightly
different definition starting with Tegra114, so the values we're
writing don't entirely make sense there anyway.

Also, simply write the whole of the register in start_cpu() rather than
doing a read-modify-write; the register is simple enough that the code
can easily construct the entire desired value.

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1

Before this commit, make terminated with an error

This bug happened when we built a board unsupporting

(harmony uses generic board but microblaze-generic does not
support it)
$ make harmony_config
Configuring for harmony board...
$ make CROSS_COMPILE=arm-linux-gnueabi-

Configuring for microblaze-generic board...
$ make CROSS_COMPILE=microblaze-linux-
Makefile:488: *** Your architecture does not support generic board.
Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file. Stop.
We had to do "make clean" before building the microblaze board.
This commit fixes this unconvenience.

Hwconfig_subarg() returns part of hwconfig string starting from

either "utmi" or "ulpi", strncmp() should be used so that a comparison

In the previous patches, we introduced the SPL/TPL fraamework.
For SD/SPI flash booting way, we introduce the SPL to enable a loader stub. The
SPL was loaded by the code from the internal on-chip ROM. The SPL initializes
the DDR according to the SPD and loads the final uboot image into DDR, then
jump to the DDR to begin execution.
For NAND booting way, the nand SPL has size limitation on some board(e.g.
P1010RDB), it can not be more than 8KB, we can call it "minimal SPL", So the
dynamic DDR driver doesn't fit into this minimum SPL. We added the TPL that is
loaded by the the minimal SPL. The TPL initializes the DDR according to the SPD
and loads the final uboot image into DDR,then jump to the DDR to begin execution.
This patch enabled SPL/TPL for P1010RDB to support starting from NAND/SD/SPI
flash with SPL framework and initializing the DDR according to SPD in the SPL/TPL.
Because the minimal SPL load the TPL to L2 SRAM and the jump to the L2 SRAM to
execute, so the section .resetvec is no longer needed.
