commit 7ccda20c9471ada13b333e6f9e52483c1db0894e Author: Hung-Te Lin hungte@chromium.org Date: Tue Mar 19 12:17:12 2013 +0800
cbfstool locate: Rename -a align switch to -P for page size
cbfstool usage change: The "-a" parameter for "cbfstool locate" has changed to "-P/--page-size".
The "locate" command was used to find a place to store ELF stage image in one memory page. Its argument "-a (alignment)" was actually specifying the page size instead of doing memory address alignment. This can be confusing when people are trying to put a blob in aligned location (ex, microcode needs to be aligned in 0x10), and see this: cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000 # output: 0x44, which does not look like aligned to 0x40000.
To prevent confusion, it's now renamed to "-P/--page-size".
Verified by building i386/axus/tc320 (with page limitation 0x40000): cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000 # output: 0x44
