Registers were organized such 21 * that (a) they can be contained in 32 bits, (b) if not, then they 22 * can be treated as two 32-bit entities, or finally (c) if they 23 * must be treated as a single 64-bit value, then this can safely 24 * be done with two 32-bit cycles. 25 * 26 * For 32-bit operations on 64-bit values, CAAM follows the same 27 * 64-bit register access conventions as it's predecessors, in that 28 * writes are "triggered" by a write to the register at the numerically 29 * higher address, thus, a full 64-bit write cycle requires a write 30 * to the lower address, followed by a write to the higher address, 31 * which will latch/execute the write cycle. 32 * 33 * For example, let's assume a SW reset of CAAM through the master 34 * configuration register. 35 * - SWRST is in bit 31 of MCFG. 36 * - MCFG begins at base+0x0000. 37 * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) 38 * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) 39 * 40 * (and on Power, the convention is 0-31, 32-63, I know...) 41 * 42 * Assuming a 64-bit write to this MCFG to perform a software reset 43 * would then require a write of 0 to base+0x0000, followed by a 44 * write of 0x80000000 to base+0x0004, which would "execute" the 45 * reset. 46 * 47 * Of course, since MCFG 63-32 is all zero, we could cheat and simply 48 * write 0x8000000 to base+0x0004, and the reset would work fine. 49 * However, since CAAM does contain some write-and-read-intended 50 * 64-bit registers, this code defines 64-bit access methods for 51 * the sake of internal consistency and simplicity, and so that a 52 * clean transition to 64-bit is possible when it becomes necessary. 53 * 54 * There are limitations to this that the developer must recognize. 55 * 32-bit architectures cannot enforce an atomic-64 operation, 56 * Therefore: 57 * 58 * - On writes, since the HW is assumed to latch the cycle on the 59 * write of the higher-numeric-address word, then ordered 60 * writes work OK. 61 * 62 * - For reads, where a register contains a relevant value of more 63 * that 32 bits, the hardware employs logic to latch the other 64 * "half" of the data until read, ensuring an accurate value. 65 * This is of particular relevance when dealing with CAAM's 66 * performance counters. 67 * 68 */ 69 70 extern bool caam_little_end; 71 extern bool caam_imx; 72 73 #define caam_to_cpu(len) \ 74 static inline u##len caam##len ## _to_cpu(u##len val) \ 75 { \ 76 if (caam_little_end) \ 77 return le##len ## _to_cpu(val); \ 78 else \ 79 return be##len ## _to_cpu(val); \ 80 } 81 82 #define cpu_to_caam(len) \ 83 static inline u##len cpu_to_caam##len(u##len val) \ 84 { \ 85 if (caam_little_end) \ 86 return cpu_to_le##len(val); \ 87 else \ 88 return cpu_to_be##len(val); \ 89 } 90 91 caam_to_cpu(16) 92 caam_to_cpu(32) 93 caam_to_cpu(64) 94 cpu_to_caam(16) 95 cpu_to_caam(32) 96 cpu_to_caam(64) 97 98 static inline void wr_reg32(void __iomem *reg, u32 data) 99 { 100 if (caam_little_end) 101 iowrite32(data, reg); 102 else 103 iowrite32be(data, reg); 104 } 105 106 static inline u32 rd_reg32(void __iomem *reg) 107 { 108 if (caam_little_end) 109 return ioread32(reg); 110 111 return ioread32be(reg); 112 } 113 114 static inline void clrsetbits_32(void __iomem *reg, u32 clear, u32 set) 115 { 116 if (caam_little_end) 117 iowrite32((ioread32(reg) & ~clear) | set, reg); 118 else 119 iowrite32be((ioread32be(reg) & ~clear) | set, reg); 120 } 121 122 /* 123 * The only users of these wr/rd_reg64 functions is the Job Ring (JR). 124 * The DMA address registers in the JR are handled differently depending on 125 * platform: 126 * 127 * 1.
