As far as I know, the parse_elf_to_stage function reads an elf file,
compute the entry and load of a stage according to the ELF header and
then copy the binary code of an elf file to the ROM file according to
the program headers. As I know, p_paddr in an program header is
unspecified but we use it to compute the address of the binary code.
That's one of the points I don't understand.
Yes. I am using the cbfstool's locate function and using cbfs code to
find the romstage and jump to it.
On ARM, if I use parse_elf_to_stage function, all the romstage elf
file from the beginning including the elf header will be copied to the
rom not only the binary code.
The other information this function generated including the cbfs_stage
header, the cbfs_file header and where this cbfs file is located are
all right. Only the binary code is wrong.
