Registers were organized such 20 * that (a) they can be contained in 32 bits, (b) if not, then they 21 * can be treated as two 32-bit entities, or finally (c) if they 22 * must be treated as a single 64-bit value, then this can safely 23 * be done with two 32-bit cycles. 24 * 25 * For 32-bit operations on 64-bit values, CAAM follows the same 26 * 64-bit register access conventions as it's predecessors, in that 27 * writes are "triggered" by a write to the register at the numerically 28 * higher address, thus, a full 64-bit write cycle requires a write 29 * to the lower address, followed by a write to the higher address, 30 * which will latch/execute the write cycle. 31 * 32 * For example, let's assume a SW reset of CAAM through the master 33 * configuration register. 34 * - SWRST is in bit 31 of MCFG. 35 * - MCFG begins at base+0x0000. 36 * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) 37 * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) 38 * 39 * (and on Power, the convention is 0-31, 32-63, I know...) 40 * 41 * Assuming a 64-bit write to this MCFG to perform a software reset 42 * would then require a write of 0 to base+0x0000, followed by a 43 * write of 0x80000000 to base+0x0004, which would "execute" the 44 * reset. 45 * 46 * Of course, since MCFG 63-32 is all zero, we could cheat and simply 47 * write 0x8000000 to base+0x0004, and the reset would work fine. 48 * However, since CAAM does contain some write-and-read-intended 49 * 64-bit registers, this code defines 64-bit access methods for 50 * the sake of internal consistency and simplicity, and so that a 51 * clean transition to 64-bit is possible when it becomes necessary. 52 * 53 * There are limitations to this that the developer must recognize. 54 * 32-bit architectures cannot enforce an atomic-64 operation, 55 * Therefore: 56 * 57 * - On writes, since the HW is assumed to latch the cycle on the 58 * write of the higher-numeric-address word, then ordered 59 * writes work OK. 60 * 61 * - For reads, where a register contains a relevant value of more 62 * that 32 bits, the hardware employs logic to latch the other 63 * "half" of the data until read, ensuring an accurate value. 64 * This is of particular relevance when dealing with CAAM's 65 * performance counters. 66 * 67 */ 68 69 extern bool caam_little_end; 70 71 #define caam_to_cpu(len) \ 72 static inline u##len caam##len ## _to_cpu(u##len val) \ 73 { \ 74 if (caam_little_end) \ 75 return le##len ## _to_cpu(val); \ 76 else \ 77 return be##len ## _to_cpu(val); \ 78 } 79 80 #define cpu_to_caam(len) \ 81 static inline u##len cpu_to_caam##len(u##len val) \ 82 { \ 83 if (caam_little_end) \ 84 return cpu_to_le##len(val); \ 85 else \ 86 return cpu_to_be##len(val); \ 87 } 88 89 caam_to_cpu(16) 90 caam_to_cpu(32) 91 caam_to_cpu(64) 92 cpu_to_caam(16) 93 cpu_to_caam(32) 94 cpu_to_caam(64) 95 96 static inline void wr_reg32(void __iomem *reg, u32 data) 97 { 98 if (caam_little_end) 99 iowrite32(data, reg); 100 else 101 iowrite32be(data, reg); 102 } 103 104 static inline u32 rd_reg32(void __iomem *reg) 105 { 106 if (caam_little_end) 107 return ioread32(reg); 108 109 return ioread32be(reg); 110 } 111 112 static inline void clrsetbits_32(void __iomem *reg, u32 clear, u32 set) 113 { 114 if (caam_little_end) 115 iowrite32((ioread32(reg) & ~clear) | set, reg); 116 else 117 iowrite32be((ioread32be(reg) & ~clear) | set, reg); 118 } 119 120 /* 121 * The only users of these wr/rd_reg64 functions is the Job Ring (JR). 122 * The DMA address registers in the JR are handled differently depending on 123 * platform: 124 * 125 * 1.
