[PATCH v1 0/3] mtd: add support for the dual-die stack parallel NOR

[PATCH v1 0/3] mtd: add support for the dual-die stack parallel NOR

[Bean Huo]

From: beanhuo <beanhuo@micron.com>

The dual-die stacked parallel NOR flash comprises the two identical dies
in parallel. the second/upper die should be selected through its unlock
cycle command addresses, maximum address line A[max]. when the 
A[max] == 1, the second/upper die is activated, when  A[max] == 0, the 
first/lower die is activated.
Because CFI table doesn't exist one entry that can tell us this is a dual
die device, I only add this information in the devicetree binding.

This patch now will update following funcitons:
otp_enter()
otp_exit()
do_write_oneword()
do_write_buffer()
do_panic_write_oneword()
do_erase_oneblock()
do_ppb_xxlock()

For the Micron dual-die stacked PNOR,since there are two dies now,
the following functions need to be changed, but not in this series
patch. Because I am not 100% sure if other parallel NOR vendors'
dual-die stacked PNOR need, still studying.
do_otp_lock()
cfi_amdstd_otp_walk()
do_erase_chip()
