Subject: [PATCH 1/3] imx-bbu-nand-fcb: Show additional information from decoded FCB
Date: Mon, 11 Oct 2021 18:53:57 -0700 [thread overview]
Message-ID: <20211012015359.933464-1-trent.piepho@igorinstitute.com> (raw)
In additional to the raw FCB fields, show some useful values calculated
from them. E.g., display the size of the bootloader image in kB based
on the configured NAND page size and number of pages in the bootloader
image. Example (all values in "()" are added):
Checksum: 0xfffffa78
