Registers were organized such 23 * that (a) they can be contained in 32 bits, (b) if not, then they 24 * can be treated as two 32-bit entities, or finally (c) if they 25 * must be treated as a single 64-bit value, then this can safely 26 * be done with two 32-bit cycles. 27 * 28 * For 32-bit operations on 64-bit values, CAAM follows the same 29 * 64-bit register access conventions as it's predecessors, in that 30 * writes are "triggered" by a write to the register at the numerically 31 * higher address, thus, a full 64-bit write cycle requires a write 32 * to the lower address, followed by a write to the higher address, 33 * which will latch/execute the write cycle. 34 * 35 * For example, let's assume a SW reset of CAAM through the master 36 * configuration register. 37 * - SWRST is in bit 31 of MCFG. 38 * - MCFG begins at base+0x0000. 39 * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) 40 * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) 41 * 42 * (and on Power, the convention is 0-31, 32-63, I know...) 43 * 44 * Assuming a 64-bit write to this MCFG to perform a software reset 45 * would then require a write of 0 to base+0x0000, followed by a 46 * write of 0x80000000 to base+0x0004, which would "execute" the 47 * reset. 48 * 49 * Of course, since MCFG 63-32 is all zero, we could cheat and simply 50 * write 0x8000000 to base+0x0004, and the reset would work fine. 51 * However, since CAAM does contain some write-and-read-intended 52 * 64-bit registers, this code defines 64-bit access methods for 53 * the sake of internal consistency and simplicity, and so that a 54 * clean transition to 64-bit is possible when it becomes necessary. 55 * 56 * There are limitations to this that the developer must recognize. 57 * 32-bit architectures cannot enforce an atomic-64 operation, 58 * Therefore: 59 * 60 * - On writes, since the HW is assumed to latch the cycle on the 61 * write of the higher-numeric-address word, then ordered 62 * writes work OK. 63 * 64 * - For reads, where a register contains a relevant value of more 65 * that 32 bits, the hardware employs logic to latch the other 66 * "half" of the data until read, ensuring an accurate value. 67 * This is of particular relevance when dealing with CAAM's 68 * performance counters. 69 * 70 */ 71 72 extern bool caam_little_end; 73 extern bool caam_imx; 74 extern size_t caam_ptr_sz; 75 76 #define caam_to_cpu(len) \ 77 static inline u##len caam##len ## _to_cpu(u##len val) \ 78 { \ 79 if (caam_little_end) \ 80 return le##len ## _to_cpu((__force __le##len)val); \ 81 else \ 82 return be##len ## _to_cpu((__force __be##len)val); \ 83 } 84 85 #define cpu_to_caam(len) \ 86 static inline u##len cpu_to_caam##len(u##len val) \ 87 { \ 88 if (caam_little_end) \ 89 return (__force u##len)cpu_to_le##len(val); \ 90 else \ 91 return (__force u##len)cpu_to_be##len(val); \ 92 } 93 94 caam_to_cpu(16) 95 caam_to_cpu(32) 96 caam_to_cpu(64) 97 cpu_to_caam(16) 98 cpu_to_caam(32) 99 cpu_to_caam(64) 100 101 static inline void wr_reg32(void __iomem *reg, u32 data) 102 { 103 if (caam_little_end) 104 iowrite32(data, reg); 105 else 106 iowrite32be(data, reg); 107 } 108 109 static inline u32 rd_reg32(void __iomem *reg) 110 { 111 if (caam_little_end) 112 return ioread32(reg); 113 114 return ioread32be(reg); 115 } 116 117 static inline void clrsetbits_32(void __iomem *reg, u32 clear, u32 set) 118 { 119 if (caam_little_end) 120 iowrite32((ioread32(reg) & ~clear) | set, reg); 121 else 122 iowrite32be((ioread32be(reg) & ~clear) | set, reg); 123 } 124 125 /* 126 * The only users of these wr/rd_reg64 functions is the Job Ring (JR). 127 * The DMA address registers in the JR are handled differently depending on 128 * platform: 129 * 130 * 1.
