looks better now, but there are still some issues

I've recently noticed that this include path is going to be deprecated in the future. All SoC specific header files should go to arch/*/mach-*/include/mach/ and a driver should use "include <mach/file.h>". I've sent a patch [1] to enable this for MIPS arch. If you rebase your patches to current next branch in u-boot-mips repo, you are having this patch included. So please use the new path.

please use CONFIG_ARCH_ATH79 as Kconfig symbol. Also with the patch mentioned above, this should be look like this:
mach-$(CONFIG_ARCH_ATH79) += ath79

you can drop all those defines. You only need to load one register with the base address and then use relative offsets in li or sw instructions.
Example:
li t0, KSEG1ADDR(AR71XX_RESET_BASE)
li t1, AR933X_RESET_REG_RESET_MODULE(t0)
..
sw t1, AR933X_RESET_REG_RESET_MODULE(t0)
or
li t0, KSEG1ADDR(AR71XX_PLL_BASE)
li t1, PLL_CPU_CONF(t0)
li t2, PLL_SEC_CONF(t0)
..
sw t1, PLL_CPU_CONF(t0)
This is more readable. It is also more efficient because you can drop a lot of instructions which repeatingly load absolute register addresses. Most of the code in this file could be simplified and optimized with this method.

please put such code in a SoC specific header file like io.h. Also use static inline function instread of macros. In genereal all register accesses should be implemented like this:
void __iomem *base = (void __iomem *)KSEG1ADDR(BASE_ADDRESS)
u32 data = readl(base + REG_OFFSET)
If you only need RST_READ in several locations, you could add a helper function something like this:
static inline u32 ath79_rst_readl(u32 offset)
{
const void __iomem *base = (void __iomem *)KSEG1ADDR(AR71XX_RESET_BASE);
return readl(base + offset);
}
