Erratum A004510 says that under certain load conditions, modified
cache lines can be discarded, causing data corruption.
To work around this, several CCSR and DCSR register updates need to be
made in a careful manner, so that there is no other transaction in
corenet when the update is made.
The update is made from a locked cacheline, with a delay before to flush
any previous activity, and a delay after to flush the CCSR/DCSR update.
We can't use a readback because that would be another corenet
transaction, which is not allowed.
We lock the subsequent cacheline to prevent it from being fetched while
we're executing the previous cacheline. It is filled with nops so that a
branch doesn't cause us to fetch another cacheline.
Ordinarily we are running in a cache-inhibited mapping at this point, so
we temporarily change that. We make it guarded so that we should never
see a speculative load, and we never do an explicit load. Thus, only the
I-cache should ever fill from this mapping, and we flush/unlock it
afterward. Thus we should avoid problems from any potential cache
aliasing between inhibited and non-inhibited mappings.
NOTE that if PAMU is used with this patch, it will need to use a
dedicated LAW as described in the erratum. This is the responsibility
of the OS that sets up PAMU.

in master's NOR flash using "saveenv" or other commands.

2. Boot location should be set to one PCIE interface by RCW.
3. RCW should configure the SerDes, PCIE interfaces correctly.
4. Must set all the cores in holdoff by RCW.
5. Must be powered on before master's boot.
For the slave module, need to finish these processes:

2. Set a specific TLB entry for the boot process.
3. Set a LAW entry with the TargetID of one PCIE for the boot.
4. Set a specific TLB entry in order to fetch ucode and ENV from

5. Set a LAW entry with the TargetID one of the PCIE ports for
ucode and ENV.
6. Slave's u-boot image should be generated specifically by
make xxxx_SRIO_PCIE_BOOT_config.
This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.
In addition, the processes are very similar between boot from SRIO and
boot from PCIE. Some configurations like the address spaces can be set to
the same. So the module of boot from PCIE was added based on the existing
module of boot from SRIO, and the following changes were needed:

nand/fsl_elbc: shrink SPL a bit by converting out_be32() to __raw_writel()
This is needed to make room for a bugfix on p1_p2_rdb_pc. A sync is used
before the final write to LSOR that initiates the transaction, to ensure
all the other set up has been completed.

PowerPC mandates SP to be 16 bytes aligned.
Furthermore, a stack frame is added, pointing to the reset vector
which may in the way when gdb is walking the stack because
the reset vector may not accessible depending on emulator settings.
Also use a temp register so gdb doesn't pick up intermediate values.

asm/clk.h was included get_peripheral_clk_rate function. But this
is not used from anywhere.
This removed asm/clk.h, and deleted include line from arch/sh/lib/time.c
