QSpi boot mode, channel 'B'

[o_scherbinin]

hello
i am making the acquaintance with MCIMX6SX-SDB kit.
investigating QSPI boot configuration

i have seen booting from QSPI2 ('A' channel, there is the 32M flash, address 0x70000000),
likewise QSPI2 channel 'B', there is the 32M flash, address 0x78000000, same.
My question is:
is there oportunity to boot from channel 'B' of QSPI2?
May i place qspi header at address 0x78000400 and

would it acceptable for "boot ROM" or i must use channel 'A' only.

Hi Oleg

seems QSPI 'A' channel is always needed as described in sect.8.6.3 QuadSPI configuration parameters:

The QuadSPI Configuration Parameters Table is built in the boot image at a fixed offset
of 0x400 from the QSPI NOR A1 base address
