Updated the spi_flash framework to handle all sizes of flashes
using bank/extd addr reg facility
The current implementation in spi_flash supports 3-byte address mode
due to this up to 16Mbytes amount of flash is able to access for those
flashes which has an actual size of > 16MB.
As most of the flashes introduces a bank/extd address registers
for accessing the flashes in 16Mbytes of banks if the flash size
is > 16Mbytes, this new scheme will add the bank selection feature
for performing write/erase operations on all flashes.

finally stoped depending on the address is equal to the _bss_end. If the end

1. The reset action stoped depending on the reset address is greater
than or equal the end address of the BSS.
2. The end address of the BSS should be 4byte aligned. Because the reset unit

For SD/SPI 2-stage bootloader, the On-Chip Rom code loads the SPL into L2 SRAM,
then jump to it to begin execution. After that, the SPL loads the final uboot
image into DDR, then jump to it to begin execution. The segment .resetvec in
the SPL and in final U-boot is useless.
So, add new symbols CONFIG_SYS_MPC85XX_NO_RESETVEC for this application.
If CONFIG_SYS_MPC85XX_NO_RESETVEC is set, the segment .resetvec is excluded
and the segment .bootpg is placed in the previous 4K of the segment .text.
