In PIC32 GPIO controller is part of PIC32 pin controller.
PIC32 has ten independently programmable ports and each with multiple pins.
Each of these pins can be configured and used as GPIO, provided they
are not in use for other peripherals.

In PIC32 pin-controller is a combined gpio-controller, pin-mux and
pin-config module. Remappable peripherals are assigned pins through
per-pin based muxing logic. And pin configuration are performed on
specific port registers which are shared along with gpio controller.
Note, non-remappable peripherals have default pins assigned thus
require no muxing.

The existing mips_io_port_base variable isn't suitable for use early
during boot since it will be stored in the .data section which may not

This patch makes sure that the flush/invalidate_dcache_range() functions
can handle corner-case calls like this -- invalidate_dcache_range(0, 0, 0);
This call is valid and is happily produced by USB EHCI code for example.
The expected behavior of the cache function(s) in this case is that they
will do no operation, since the size is zero.

The current implementation though has a problem where such invocation will
result in a hard CPU hang. This is because under such conditions, where the
start_addr = 0 and stop = 0, the addr = 0 and aend = 0xffffffe0 . The loop
will then try to iterate over the entire address space, which in itself is
wrong. But iterating over the entire address space might also hit some odd
address which will cause bus hang. The later happens on the Atheros MIPS.

This provides a good-looking font for user prompts.

Signed-off-by: Simon Glass <sjg@chromium.org>

The existing 8x16 font is adequate for most purposes. It is small and fast.
However for boot screens where information must be presented to the user,
the console font is not ideal. Common requirements are larger and
better-looking fonts.

This console driver can use TrueType fonts built into U-Boot, and render
them at any size. This can be used in scripts to place text as needed on
the display.

This driver is not really designed to operate with the command line. Much
of U-Boot expects a fixed-width font. But to keep things working correctly,
rudimentary support for the console is provided. The main missing feature is
support for command-line editing.

With anti-aliased fonts we need a more fine-grained horizontal position
than a single pixel. Characters can be positioned to start part-way through
a pixel, with anti-aliasing (greyscale edges) taking care of the visual
effect.

To cope with this, use fractional units (1/256 pixel) for horizontal
positions in the text console.

testing. If the boardenv doesn't specify a set of sizes, the built-in list

Currently, bad patterns are only honored when executing a shell command.
Other cases, such as the initial boot-up of U-Boot or when interacting
with command output rather than gathering all output prior to the shell
prompt, do not currently look for bad patterns in console output. This
patch makes sure that bad patterns are honored everywhere.

One benefit of this change is that if U-Boot sandbox fails to start up,
the error message it emits can be caught immediately, rather than relying
on a (long) timeout when waiting for the expected signon message and/or
command prompt.
