| | | | | | | | | | | | | | | | | | | | The RX/TX address is always the same regardless of the size of the access. That means there is no dedicated "16bit" or "32bit" MMR. Trying to use these currently leads to compile errors. So change everything to use the right MMR define. Signed-off-by: Bob Liu <lliubbo@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: merge kernel init memory back into main memory regionSonic Zhang2010-10-221-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the kernel's init section is merged back into the main memory region during boot (which it should since that is how we've laid out the kernel linker map), we want to make sure that these aren't counted as independent regions. Otherwise, if a large mapping is attempted which starts in the init region and extends into the main memory region, the access_ok func will deny it. This leads to weird messages during runtime like "unable to map xxx library" from the ldso but upon running the application again, everything works fine. So if the address of the end of the init region is the same as the start of the main memory region, simply enlarge the memory region to include the init region.

| * Blackfin: gpio: add peripheral group checksteven miao2010-10-221-67/+118
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many Blackfin parts group sets of pins into a single functional unit. This means you cannot use different pins within a group for different peripherals. Our resource conflict checking thus far has been limited to individual pins, so if someone tried to grab a different pin from the same group, it would be allowed while silently changing the other pins in the same group. One common example is the pin set PG12 - PG15 on BF51x parts. They may either be used with SPI0 (1st function), or they may be used with PTP/PWM/AMS3 (3rd function). Ideally, we'd like to use PG12 - PG14 for SPI0 while using PG15 with AMS3, but the hardware does not permit this. In the past, the software would allow the pins to be requested this way, but ultimately things like the Blackfin SPI driver would stop working when the hardware rerouted to a different peripheral.

| * Blackfin: add new cacheflush syscallSonic Zhang2010-10-227-3/+44
| | | | | | | | | | | | | | | | | | | | | | | | Flushing caches sometimes requires anomaly workarounds which require supervisor-only insns. Normally we don't need to flush caches from userspace so this isn't a problem, but when gcc generates trampolines on the stack, we do. So add a new syscall for gcc to use modeled after the mips version. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | The BF54x processor has a ton of on-chip peripherals and in order to support them all, the u-boot image is quite large. So give it 512KiB in all bootable flashes to make our lives easier. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Both AD0 and AD1 are of voltage 3.3V, which means the i2c address should be 0x2F. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | | | Nothing actually needs to use these MMRs (as direct cache manipulation is done with the DTEST MMRs), so simply hide the read funcs behind the anomaly define.

| | | | | | | | | | | | | | | | | | The num_chipselect field for on-chip Blackfin SPI buses is supposed to be 1 larger than the number of actual CSs available.

| * Blackfin: SIC: BF537: change default data/error relative prioritiesMichael Hennerich2010-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some peripherals might generate an error interrupt shortly after the data interrupt due to the fact that the peripheral isn't serviced fast enough. In most cases this isn't a problem and is expected behavior. This hasn't been a problem on most parts since you simply don't request the error interrupt (or you leave it disabled while there is an expected state) and do the peripheral status checking in the data interrupt. The Blackfin SIC allows people to prioritize data and error interrupts, and the Blackfin CEC allows interrupts of equal or higher priority to nest. The current default settings gives error interrupts a higher priority than data interrupts. So if an error occurs while processing the data interrupt, it will be serviced immediately. However, the error interrupt on the BF537 SIC cannot be enabled on a per-peripheral basis. Once the error interrupt is enabled for one peripheral, it is automatically enabled for all peripherals. Therefore lower the default multiplexed error interrupt priority so most people need not worry themselves with this issue.
