ARM: proc-v7: move CPU errata out of line
Rather than having a long sprawling __v7_setup function, which is hard
to maintain properly, move the CPU errata out of line.
While doing this, it was discovered that the Cortex-A15 errata had been
incorrectly added:
ldr r10, =0x00000c08 @ Cortex-A8 primary part number
teq r0, r10
bne 2f
/* Cortex-A8 errata */
b 3f
2: ldr r10, =0x00000c09 @ Cortex-A9 primary part number
teq r0, r10
bne 3f
/* Cortex-A9 errata */
3: ldr r10, =0x00000c0f @ Cortex-A15 primary part number
teq r0, r10
bne 4f
/* Cortex-A15 errata */
4:
This results in the Cortex-A15 test always being executed after the
Cortex-A8 and Cortex-A9 errata, which is obviously not what is intended.
The 'b 3f' labels should have been updated to 'b 4f'. The new structure
of:
/* Cortex-A8 Errata */
ldr r10, =0x00000c08 @ Cortex-A8 primary part number
teq r0, r10
beq __ca8_errata
/* Cortex-A9 Errata */
ldr r10, =0x00000c09 @ Cortex-A9 primary part number
teq r0, r10
beq __ca9_errata
/* Cortex-A15 Errata */
ldr r10, =0x00000c0f @ Cortex-A15 primary part number
teq r0, r10
beq __ca15_errata
__errata_finish:
is much cleaner and easier to see that this kind of thing doesn't
happen.
