There are several reasons for this:
The first and most important reason is the size of bootblock. As I say
in the last mail, the internal SRAM for holding the first sector of
NAND Flash is very small. For example, Samsung 2410 CPU only has a 4K
Second, ARM CPU is not as powerful as X86. The decompress function
will need much more time than that on X86.
Is my code for using a binary file to add stage to the romfile fine?
If so, I will move forward to the ramstage.
