| |
The CPUs in these SoCs support MIPS32 R2, and allow ebase relocation. Even if the default exception base of 0x80000000 is used, the MIPS_GENERIC load address of 0x80100000 leaves sufficient space to not need an extra 0x400 bytes of padding.
Suggested-by: Olliver Schinagl <oliver@schinagl.nl> Signed-off-by: Sander Vanheule <sander@svanheule.net> --- Olliver has suggested to make this change, in order to reduce the delta with a fully generic MIPS kernel. I hope the patch description makes sense, as I based the argumentation on the behaviour of the code, and similar commits 7d6d28377783 ("MIPS: Loongson64: select NO_EXCEPT_FILL") and dd54dedd947d ("MIPS: BCM47XX: select NO_EXCEPT_FILL"). The change was tested on an RTL8380 and an RTL8393 device, where it appears to work as expected.
Best, Sander
