Subject: [PATCH] xtensa: fix text relocations
|
|
|
|
The commit 5e08f1968316 ("Don't always update text in !pic_with_got case")
|
|
changed good_32bit_resolved_reloc to not do endianness swapping for
|
|
relocated entries in the text segment. This broke little-endian xtensa
|
|
FLAT images which after this change fail to start with the following
|
|
message:
|
|
|
|
binfmt_flat: reloc outside program 0x24c80100 (0 - 0x6e430/0x56a20)
|
|
|
|
Fix it by preserving 'update_text' when building for xtensa.
|
|
|
|
