Subject: [PATCH] ld: pru: Fix resource_table output section alignment
|
|
|
|
My commit 261980de18b added alignment for the resource table symbol.
|
|
But it is wrong. The Linux remoteproc driver loads and interprets the
|
|
contents of the .resource_table ELF section, not of a table symbol.
|
|
|
|
Without this patch, if the linker happens to output padding for symbol
|
|
alignment, then the resource table contents as viewed by the kernel
|
|
loader would "shift" and look corrupted.
|
|
|
|
ld/ChangeLog:
|
|
|
|
* scripttempl/pru.sc (.resource_table): Align the output
|
|
section, not the first symbol.
