Registers were organized such * that (a) they can be contained in 32 bits, (b) if not, then they * can be treated as two 32-bit entities, or finally (c) if they * must be treated as a single 64-bit value, then this can safely * be done with two 32-bit cycles. * * For 32-bit operations on 64-bit values, CAAM follows the same * 64-bit register access conventions as it's predecessors, in that * writes are "triggered" by a write to the register at the numerically * higher address, thus, a full 64-bit write cycle requires a write * to the lower address, followed by a write to the higher address, * which will latch/execute the write cycle. * * For example, let's assume a SW reset of CAAM through the master * configuration register. * - SWRST is in bit 31 of MCFG. * - MCFG begins at base+0x0000. * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) * * (and on Power, the convention is 0-31, 32-63, I know...) * * Assuming a 64-bit write to this MCFG to perform a software reset * would then require a write of 0 to base+0x0000, followed by a * write of 0x80000000 to base+0x0004, which would "execute" the * reset. * * Of course, since MCFG 63-32 is all zero, we could cheat and simply * write 0x8000000 to base+0x0004, and the reset would work fine. * However, since CAAM does contain some write-and-read-intended * 64-bit registers, this code defines 64-bit access methods for * the sake of internal consistency and simplicity, and so that a * clean transition to 64-bit is possible when it becomes necessary. * * There are limitations to this that the developer must recognize. * 32-bit architectures cannot enforce an atomic-64 operation, * Therefore: * * - On writes, since the HW is assumed to latch the cycle on the * write of the higher-numeric-address word, then ordered * writes work OK. * * - For reads, where a register contains a relevant value of more * that 32 bits, the hardware employs logic to latch the other * "half" of the data until read, ensuring an accurate value. * This is of particular relevance when dealing with CAAM's * performance counters. * */ extern bool caam_little_end; extern bool caam_imx; extern size_t caam_ptr_sz; #define caam_to_cpu(len) \ static inline u##len caam##len ## _to_cpu(u##len val) \ { \ if (caam_little_end) \ return le##len ## _to_cpu((__force __le##len)val); \ else \ return be##len ## _to_cpu((__force __be##len)val); \ } #define cpu_to_caam(len) \ static inline u##len cpu_to_caam##len(u##len val) \ { \ if (caam_little_end) \ return (__force u##len)cpu_to_le##len(val); \ else \ return (__force u##len)cpu_to_be##len(val); \ } caam_to_cpu(16) caam_to_cpu(32) caam_to_cpu(64) cpu_to_caam(16) cpu_to_caam(32) cpu_to_caam(64) static inline void wr_reg32(void __iomem *reg, u32 data) { if (caam_little_end) iowrite32(data, reg); else iowrite32be(data, reg); } static inline u32 rd_reg32(void __iomem *reg) { if (caam_little_end) return ioread32(reg); return ioread32be(reg); } static inline void clrsetbits_32(void __iomem *reg, u32 clear, u32 set) { if (caam_little_end) iowrite32((ioread32(reg) & ~clear) | set, reg); else iowrite32be((ioread32be(reg) & ~clear) | set, reg); } /* * The only users of these wr/rd_reg64 functions is the Job Ring (JR). * The DMA address registers in the JR are handled differently depending on * platform: * * 1.
