Helge Deller c42813b71a parisc: Fix unaligned-access crash in bootloader ... Kernel v5.14 has various changes to optimize unaligned memory accesses, e.g. commit 0652035a57 ("asm-generic: unaligned: remove byteshift helpers"). Those changes triggered an unalignment-exception and thus crashed the bootloader on parisc because the unaligned "output_len" variable now suddenly was read word-wise while it was read byte-wise in the past. Fix this issue by declaring the external output_len variable as char which then forces the compiler to generate byte-accesses.
