Registers were organized such 22 * that (a) they can be contained in 32 bits, (b) if not, then they 23 * can be treated as two 32-bit entities, or finally (c) if they 24 * must be treated as a single 64-bit value, then this can safely 25 * be done with two 32-bit cycles. 26 * 27 * For 32-bit operations on 64-bit values, CAAM follows the same 28 * 64-bit register access conventions as it's predecessors, in that 29 * writes are "triggered" by a write to the register at the numerically 30 * higher address, thus, a full 64-bit write cycle requires a write 31 * to the lower address, followed by a write to the higher address, 32 * which will latch/execute the write cycle. 33 * 34 * For example, let's assume a SW reset of CAAM through the master 35 * configuration register. 36 * - SWRST is in bit 31 of MCFG. 37 * - MCFG begins at base+0x0000. 38 * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) 39 * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) 40 * 41 * (and on Power, the convention is 0-31, 32-63, I know...) 42 * 43 * Assuming a 64-bit write to this MCFG to perform a software reset 44 * would then require a write of 0 to base+0x0000, followed by a 45 * write of 0x80000000 to base+0x0004, which would "execute" the 46 * reset. 47 * 48 * Of course, since MCFG 63-32 is all zero, we could cheat and simply 49 * write 0x8000000 to base+0x0004, and the reset would work fine. 50 * However, since CAAM does contain some write-and-read-intended 51 * 64-bit registers, this code defines 64-bit access methods for 52 * the sake of internal consistency and simplicity, and so that a 53 * clean transition to 64-bit is possible when it becomes necessary. 54 * 55 * There are limitations to this that the developer must recognize. 56 * 32-bit architectures cannot enforce an atomic-64 operation, 57 * Therefore: 58 * 59 * - On writes, since the HW is assumed to latch the cycle on the 60 * write of the higher-numeric-address word, then ordered 61 * writes work OK. 62 * 63 * - For reads, where a register contains a relevant value of more 64 * that 32 bits, the hardware employs logic to latch the other 65 * "half" of the data until read, ensuring an accurate value. 66 * This is of particular relevance when dealing with CAAM's 67 * performance counters. 68 * 69 */ 70 71 extern bool caam_little_end; 72 extern bool caam_imx; 73 74 #define caam_to_cpu(len) \ 75 static inline u##len caam##len ## _to_cpu(u##len val) \ 76 { \ 77 if (caam_little_end) \ 78 return le##len ## _to_cpu((__force __le##len)val); \ 79 else \ 80 return be##len ## _to_cpu((__force __be##len)val); \ 81 } 82 83 #define cpu_to_caam(len) \ 84 static inline u##len cpu_to_caam##len(u##len val) \ 85 { \ 86 if (caam_little_end) \ 87 return (__force u##len)cpu_to_le##len(val); \ 88 else \ 89 return (__force u##len)cpu_to_be##len(val); \ 90 } 91 92 caam_to_cpu(16) 93 caam_to_cpu(32) 94 caam_to_cpu(64) 95 cpu_to_caam(16) 96 cpu_to_caam(32) 97 cpu_to_caam(64) 98 99 static inline void wr_reg32(void __iomem *reg, u32 data) 100 { 101 if (caam_little_end) 102 iowrite32(data, reg); 103 else 104 iowrite32be(data, reg); 105 } 106 107 static inline u32 rd_reg32(void __iomem *reg) 108 { 109 if (caam_little_end) 110 return ioread32(reg); 111 112 return ioread32be(reg); 113 } 114 115 static inline void clrsetbits_32(void __iomem *reg, u32 clear, u32 set) 116 { 117 if (caam_little_end) 118 iowrite32((ioread32(reg) & ~clear) | set, reg); 119 else 120 iowrite32be((ioread32be(reg) & ~clear) | set, reg); 121 } 122 123 /* 124 * The only users of these wr/rd_reg64 functions is the Job Ring (JR). 125 * The DMA address registers in the JR are handled differently depending on 126 * platform: 127 * 128 * 1.
