Registers were organized such 19 * that (a) they can be contained in 32 bits, (b) if not, then they 20 * can be treated as two 32-bit entities, or finally (c) if they 21 * must be treated as a single 64-bit value, then this can safely 22 * be done with two 32-bit cycles. 23 * 24 * For 32-bit operations on 64-bit values, CAAM follows the same 25 * 64-bit register access conventions as it's predecessors, in that 26 * writes are "triggered" by a write to the register at the numerically 27 * higher address, thus, a full 64-bit write cycle requires a write 28 * to the lower address, followed by a write to the higher address, 29 * which will latch/execute the write cycle. 30 * 31 * For example, let's assume a SW reset of CAAM through the master 32 * configuration register. 33 * - SWRST is in bit 31 of MCFG. 34 * - MCFG begins at base+0x0000. 35 * - Bits 63-32 are a 32-bit word at base+0x0000 (numerically-lower) 36 * - Bits 31-0 are a 32-bit word at base+0x0004 (numerically-higher) 37 * 38 * (and on Power, the convention is 0-31, 32-63, I know...) 39 * 40 * Assuming a 64-bit write to this MCFG to perform a software reset 41 * would then require a write of 0 to base+0x0000, followed by a 42 * write of 0x80000000 to base+0x0004, which would "execute" the 43 * reset. 44 * 45 * Of course, since MCFG 63-32 is all zero, we could cheat and simply 46 * write 0x8000000 to base+0x0004, and the reset would work fine. 47 * However, since CAAM does contain some write-and-read-intended 48 * 64-bit registers, this code defines 64-bit access methods for 49 * the sake of internal consistency and simplicity, and so that a 50 * clean transition to 64-bit is possible when it becomes necessary. 51 * 52 * There are limitations to this that the developer must recognize. 53 * 32-bit architectures cannot enforce an atomic-64 operation, 54 * Therefore: 55 * 56 * - On writes, since the HW is assumed to latch the cycle on the 57 * write of the higher-numeric-address word, then ordered 58 * writes work OK. 59 * 60 * - For reads, where a register contains a relevant value of more 61 * that 32 bits, the hardware employs logic to latch the other 62 * "half" of the data until read, ensuring an accurate value. 63 * This is of particular relevance when dealing with CAAM's 64 * performance counters. 65 * 66 */ 67 68 #ifdef __BIG_ENDIAN 69 #define wr_reg32(reg, data) out_be32(reg, data) 70 #define rd_reg32(reg) in_be32(reg) 71 #ifdef CONFIG_64BIT 72 #define wr_reg64(reg, data) out_be64(reg, data) 73 #define rd_reg64(reg) in_be64(reg) 74 #endif 75 #else 76 #ifdef __LITTLE_ENDIAN 77 #define wr_reg32(reg, data) __raw_writel(data, reg) 78 #define rd_reg32(reg) __raw_readl(reg) 79 #ifdef CONFIG_64BIT 80 #define wr_reg64(reg, data) __raw_writeq(data, reg) 81 #define rd_reg64(reg) __raw_readq(reg) 82 #endif 83 #endif 84 #endif 85 86 #ifndef CONFIG_64BIT 87 #ifdef __BIG_ENDIAN 88 static inline void wr_reg64(u64 __iomem *reg, u64 data) 89 { 90 wr_reg32((u32 __iomem *)reg, (data & 0xffffffff00000000ull) >> 32);
