fastboot: ARM: OMAP5: Enable reboot-bootloader
Implemented fb_set_reboot_flag() for OMAP5 to set
an environment variable 'dofastboot' when reboot-bootloader called.
This environment variable will be checked in boot command and fastboot
will be called if the variable is set.
If the bootcmd env variable of OMAP5 common is overwritten with board-specific

This was originally intended for DRA7 platform, but now applies to all OMAP5.

access in the cadence QSPI driver which is hard to prevent since the
data is written into a 4-byte wide FIFO. This patch fixes this problem
by changing the behavior of the last sector write (not sector aligned).
The new code is even simpler and copies the source data into the temp
buffer and now uses the temp buffer to write the complete sector. So
only one SPI sector write is used now instead of 2 in the old version.

armv8/fsl-lsch3: Add Freescale Debug Server driver
The Debug Server driver is responsible for loading the Debug
server FW on the Service Processor (Cortex-A5 core) on LS2085A like
SoCs and then polling for the successful initialization of the same.
TOP MEM HIDE is adjusted to ensure the space required by Debug Server
FW is accounted for. MC uses the DDR area which is calculated as:
MC DDR region start = Top of DDR - area reserved by Debug Server FW
