ppc32 boot fails when boot and stack allocations are in some places

[Jiří Zárevúcky]

Prior to commit ​d59718e2, this is easily reproducible by adding . = . + 8192; into the kernel linker script, leaving enough space for kernel stack to be allocated in the created gap. Instead of booting properly and printing output, kernel will keep running but fills the screen with garbage.

If the stack is put after boot allocations, this does not occur, so that's what the workaround commit does.
However, the problem reoccurs if balloc is moved some distance (<600kB) from its usual position.

Could you please retest this with d1da1ff2de1cccc51856404f676142f7deb1cf54?

Hi, it doesn't seem to fix this.
