In commit 104a6a7ccf support was added
for Thumb2. It added do_execute() as a way to provide arch dependent
calling veneers for use in "go" and thumb2_execute() as the thumb2 to
arm veneer.
But thumb2_execute() isn't necessary as gcc generates a proper calling
sequence from a standard function pointer call. Thumb2 barebox is
compiled with the AAPCS ABI which requires this.
It also had a bug and didn't pass the arguments properly, but code
execute via "go" rarely uses arguments so this wasn't very noticeable.
Since thumb2 was always the only user of do_execute(), go ahead and
delete that too.

Instead of writing one word to the txfifo and then wait until
one is received in the rxfifo we can write while the txfifos
are not full and read as long the rxfifos contain data. This
makes transfers for the m25p80 driver around 7 times faster
here.
Unlike the last version this time we only optimize the common
case with 8 bits per word and SPI_LSB_FIRST cleared. The other
cases would require more bit shuffling of the data.

This is the Microchip version of the Atmel 24c1024, which is already
supported. The key difference between them is that the I2C address
bit used to select between the two banks is bit 2 for the 1025 and not
bit 0 as in the 1024.
Add a flag to describe this difference.

Since there is no OF support in the xloader on socfpga it uses the
platform_data system. There needs to be a way to supply the
equivalent of the DT property bus-width this way to support devices
that need to use a smaller bus.
So that we don't need to put every flag that might get added to the
MMC_CAP list into platform_data, just put the bus width ones into
platform_data.
The socfpga dts sources specify a bus-width of 4 so use that in the
platform_data for socfpga.

The OF code for parsing bus-width would only add the specified width
to those the driver might have already set capability flags for.
Because of this, if the driver had set 8 or 4 bit width, it wasn't
possible for the DT to specify that fewer pins were used on the board
and a smaller width was necessary.
Change this so the width in the DT overrides whatever widths the
driver says it supports. There is no reason to have an incorrect
device tree and it makes far more sense for the DT to override the
driver default than for the driver default to override the DT.
The widths the driver puts in host_caps before calling mci_of_parse()
are considered the default if the DT doesn't specify bus-width. This
should cause the least amount of change to existing boards, as despite
a comment that no bus-width meant to use 1 bit, using the driver
default is what was really happening.
Unfortunately, half of existing drivers default to the largest width
they support while the other half default to the smallest. Boards
should just stick the width in the device tree.

Instead of having a fixed array of fonts register the fonts dynamically.
This allows easier adding of fonts to the tree since only one file per
font has to be added and no other files modified.
Currently we have to register the fonts very early before the first
framebuffer is registered. This is because of our limited
dev_add_param_enum() which wants to know the number of elements when
called, so we can't add elements once after we've called
dev_add_param_enum(). Maybe a dev_add_param_array() has to be created
whithout this limitation, but that's left for a future exercise.

O_CREAT and O_RWSIZE_8 are both defined as 0100. Fix this by moving the
O_RWSIZE_* flags to unused bits.
This bug leads to incomplete writes when the destination file is created
and mem_write is involved, for example with the memcpy command:
memcpy -s /some/file -d /dev/ram0 0 0 10
In this case only 8 bytes will be copied and it will be done using 8
byte accesses which may not work properly if the destination is not
sufficiently aligned, i.e.:
memcpy -s /some/file -d /dev/ram0 0 1 8

remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

putting an error pointer into strerror can be a bit confusing since
strerror takes a positive error code but PTR_ERR returns a negative
number, so we have to do strerror(-PTR_ERR(errp)). Some places got
this wrong already, so introduce a strerrorp function which directly
takes an error pointer.

endian: Always evaluate arguments.
In barebox.git/drivers/usb/core/usb.c,
function usb_parse_config() we have had
le16_to_cpus(&(dev->config.wTotalLength));
which evaluates to "do { } while (0)" on little endian,
so struct usb_configuration field misuse will never
be discovered on little endian.
Therefore, always evaluate the arguments to nop endian
transformation operations.
