| | | | | | | | | | | | | | | | | | | | | | Implement GPIO hotplugging via TMIO_MMC_HAS_COLD_CD for AG5EVM SDHI0. This is possible now when INTCA is used for IRQ triggering on sh73a0. Without INTCA IRQ support we are left with the GIC hardware block that does not support dealing with active low interrupt sources.

| | | | | | | | | | | | | | | | | | | | | | Improve IRQ triggering support by making use of the macro INTC_IRQ_PINS_32() for INTCA on sh73a0. Unfortunately it is not as easy as just using the macro as-is, we need to do mask and unmaks in the GIC but configure other bits and ack in INTCA. Update GPIO IRQ mappings while at it.

| * ARM: mach-shmobile: sh73a0 GPIO IRQ supportMagnus Damm2011-11-051-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for sh73a0 GPIO IRQs by making use of the PFC GPIO IRQ feature. Only IRQ pins are supported at this time. In the future when PINT interrupts also are supported properly we can easily extend the table with such information. Also, the sh73a0 is currently making use of the GIC for external interrupt which is rather unflexible when it comes to triggering configuration at this point.

There are different kinds of FPGAs used on the boards, but only two are currently standard: "pixis", "ngpixis", and "qixis". Although there are minor differences among the boards that have one kind of FPGA, most of the functionality is the same, so it makes sense to create common compatibility strings. We also need to update the P1022DS platform file, because the compatible string for its PIXIS node has changed. This means that older kernels are not compatible with newer device trees. This is not a real problem, however, since that particular function doesn't work anyway. When the DIU is active, the PIXIS is in "indirect mode", and so cannot be accessed as a memory-mapped device.

The single entry is important because when we bring up secondary cores they need to ensure any data structure they need to access (eg PACA or stack) is always mapped. So we really need to determine what size will actually be mapped by the first TLB entry to ensure we limit early memory references to that region. We refactor the map_mem_in_cams() code to provider a helper function that we can utilize to determine the size of the first TLB entry while taking into account size and alignment constraints.

However, on Book-E 64 parts the initial linear mapping is quite large (1G) so its quite reasonable that mem= is set smaller than that. We need to parse the command line for mem= limit and constrain the amount of memory we map initially by it if need be. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
