k2hk EVM is based on Texas Instruments Keystone2 Hawking/Kepler SoC. Keystone2 SoC has ARM v7 Cortex-A15 MPCore processor. Please refer the ti/k2hk_evm/README for details on the board, build and other information.

This patch add support for keystone architecture and k2hk evm.

+#define reg_setbits(reg, bits) \

+#define reg_clrbits(reg, bits) \

• __raw_writel((__raw_readl(reg) & ~(bits)) , (reg));

I think the first one is just another way of saying clrsetbits_le32 (or can be re-written as such), but reg_setbits/reg_clrbits are convertable to setbits/clrbits.
