Subject: fsl_elbc_nand: Hard-code the FBAR/FPAR split.
X-Git-Tag: v2025.01-rc5-pxa1908~21997^2~12

fsl_elbc_nand: Hard-code the FBAR/FPAR split.

The hardware has separate registers for block and page-within-block,
but the division between the two has no apparent relation to the
actual erase block size of the NAND chip.
