Hi,
I ran into trouble when booting huge compressed images via bootm. do_bootm uses a fixed maximum size for the uncompressed data of 0x400000 bytes. That's not enough for our images (about uncompressed 9MB VxWorks image).
Is there any reason for the 4MB limiting? I'd like to post a patch that fixes this issue:
a) just increase the unc_len variable to e.g. 16MB b) add a define with default to board config file (CONFIG_MAX_BOOTM_UNC_LEN). When not defined in config file, 0x400000 is used c) set unc_len to mem size :-) So user must know what he is doing.
What do you like best?
BTW: When the uncompressed data is more than the unc_len limit no error is reported. The uncompressed data is just truncated leading to corrupted uncompressed data. Should that be fixed, too?
Regards Matthias
