109 * Notes:
110 * 1) The SPI registers are split into two blocks, one offset from the
111 * MSP_SPI_BASE by 0x00 and the other offset from the MSP_SPI_BASE by
112 * 0x68. The SPI driver definitions for the register must be aware
113 * of this.
114 * 2) The block copy engine register are divided into two regions, one
115 * for the control/configuration of the engine proper and one for the
116 * values of the descriptors used in the copy process. These have
117 * different base defines (CTRL_BASE vs DESC_BASE)
118 * 3) These constants are for physical addresses which means that they
119 * work correctly with "ioremap" and friends. This means that device
120 * drivers will need to remap these addresses using ioremap and perhaps
121 * the readw/writew macros. Or they could use the regptr() macro
122 * defined below, but the readw/writew calls are the correct thing.
123 * 4) The UARTs have an additional status register offset from the base
124 * address. This register isn't used in the standard 8250 driver but
125 * may be used in other software. Consult the hardware datasheet for
126 * offset details.
127 * 5) For some unknown reason the security engine (MSP_SEC_BASE) registers
128 * start at an offset of 0x84 from the base address but the block of
129 * registers before this is reserved for the security engine. The
130 * driver will have to be aware of this but it makes the register
131 * definitions line up better with the documentation.
