u32 get_cpu_rev(void) {

• int system_rev = 0x61000 | CHIP_REV_1_0;

• int reg = readl(ANATOP_BASE_ADDR + 0x260) & 0xFF;

Can we get a register overlay instead of the 'ANATOP_BASE_ADDR + 0x260'? Like in the rest of the file, e.g.

readl(&fuse->mac_addr_high); writel(0x00000000, &aips1->opacr0);

Best regards
