* [ARM] pxa: build arch/arm/plat-pxa/mfp.c only when PXA3xx or ARCH_MMP definedEric Miao2009-03-261-1/+3
| | | | | | | | | arch/arm/plat-pxa/mfp.c is not intended to be use by PXA25x/PXA27x, make it explicit here only for use by PXA3xx or ARCH_MMP.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | """The Marvell® PXA168 processor is the first in a family of application processors targeted at mass market opportunities in computing and consumer devices. It balances high computing and multimedia performance with low power consumption to support extended battery life, and includes a wealth of integrated peripherals to reduce overall BOM cost .... """ See http://www.marvell.com/featured/pxa168.jsp for more information. 1. Marvell Mohawk core is a hybrid of xscale3 and its own ARM core, there are many enhancements like instructions for flushing the whole D-cache, and so on 2. Clock reuses Russell's common clkdev, and added the basic support for UART1/2. 3. Devices are a bit different from the 'mach-pxa' way, the platform devices are now dynamically allocated only when necessary (i.e. when pxa_register_device() is called). Description for each device are stored in an array of 'struct pxa_device_desc'. Now that: a. this array of device description is marked with __initdata and can be freed up system is fully up b. which means board code has to add all needed devices early in his initializing function c. platform specific data can now be marked as __initdata since they are allocated and copied by platform_device_add_data() 4. only the basic UART1/2/3 are added, more devices will come later.

Instead of #include this file, let's: 1. include the specific <mach/regs-*.h> with care (if that's absolutely necessary) 2. define the registers in the driver, make cleanly defined API to expose the register access to external with sufficient reason Signed-off-by: Eric Miao <eric.miao@marvell.com>

By doing this, we are now able to move the PCMCIA related definitions out of pxa-regs.h and back into pxa2xx_base.c. As a result, remove that reference of _PCMCIA1IO in arch/arm/mach-pxa/viper.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Driver code where pxa_request_dma() is called will most likely reference DMA registers as well, and it is really unnecessary to include pxa-regs.h just for this. Move the definitions into <mach/dma.h> and make relevant drivers include it instead of <mach/pxa-regs.h>. 2. Introduce DMAC_REGS_VIRT as the virtual address base for these DMA registers. This allows later processors to re-use the same IP while registers may start at different I/O address. Signed-off-by: Eric Miao <eric.miao@marvell.com>
