DIVIL Register Descriptions
5.6.2.9
See Section 4.6.1 "LBARs and Comparators" on page 97
for operational details.
The NAND Flash control registers take 16 bytes of I/O
space. NOR Flash maps into some multiple of 4k bytes.
There are two forms of this LBAR depending on the space,
memory or I/O, Flash Device 0 is mapped into. Space is
determined by bit 34 of the LBAR.
