The GPIO bank name for banks J and K are not correct when using the
'gpio' command from the console.
The driver derives the bank name from the device tree instance string by
using the instance value and adding 'A': gpio0@xxaddrxx is Bank A,
gpio1@yyaddryy is Bank B and so on.
On the PIC32, there is no Bank I so instances 8 and 9 need to be
incremented as a minimum change.
An alternative (less opaque) implementation would be to use a bank-name
property instead but this would require modifying the driver code too.
Signed-off-by: John Robertson <john.robertson@simiatec.com>
GPIO state cannot be changed via the device tree (e.g. with gpio-hog) or
using the 'gpio' command from the console.
The root cause is a discrepancy between the driver and the device tree:
the driver code expects an absolute I/O address in the <reg> property,
while the device tree defines the address relative to a declaration in
the parent pinctrl node.
Changing the device tree to fix a driver issue would normally be wrong,
however:
- I have run the first version of U-Boot in which this driver appears
(v2016.03) and the same problem exists, so this is not a regression;
- There is no code that references a parent device tree node that might
suggest the intent of the author was to parse the DT as it exists now;
- The equivalent Linux PIC32 GPIO driver also uses absolute addresses
for the GPIO <reg> property. This change brings the U-Boot DT more
into line with Linux.
Additionally, the data sheet (Microchip ref. 60001361H) shows that the
register set to control a GPIO bank spans 0xE0 bytes, but the device
tree specified size is only 0x48 bytes.

change_k0_cca() is called multiple times. Move the code for
changing to KSEG1 to a macro to avoid code duplication.
Also fix missing change to KSEG1 when changing to CONF_CM_CACHABLE_COW.

Since commit 703ec9ddf9 ("MIPS: Stop building position independent code")
the relocation code was completely reworked and removed from start.S.
Remove some left-overs of the old code.

This patch adds __weak to invalidate_dcache_range() in lib/cache.c. This
makes it possible to overwrite this function by a platforms specific
version, which will be done for Octeon.

This patch adds __weak to flush_cache() in lib/cache.c. This makes it
possible to overwrite this function by a platforms specific version,
like done with the Octeon base port.

This patch enables the usage of CONFIG_MIPS_L2_CACHE without
CONFIG_MIPS_CM, which is what is needed for the newly added Octeon
platform.

This patch changes the R_MIPS_NONE define from 0 to a magic value. This
makes it possible to better detect any forbidden pre-relocation usage
of BSS variables, as they are often zero'ed and then relocation is
stopped too early.
Additionally the error message is improved to also print the faulting
address. This helps finding the root-cause for this breakage by
comparing this address with the values in System.map.
This patch helps a lot when working on pre-relocation code, like the
Octeon DDR init code, where such variables have hit me multiple times
now.

This patch opts-out the compilation of get_tbclk() if
CONFIG_SYS_MIPS_TIMER_FREQ is not defined. This is used on the Octeon
platform, where the weak get_tbclk() function is overwritten by its
platform specific one.
