global: Convert simple_strtoul() with decimal to dectoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 10 in each call. Add a new
dectoul() function and update the code to use it.

common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

drivers: serial: probe all uart devices

2021-01-16T19:49:09+00:00

U-Boot DM model probe only single device at a time
which is enabled and configured using device tree
or platform data method.

PL011 UART IP is SBSA compliant and firmware does the
serial port set-up, initialization and let the kernel use
UART port for sending and receiving characters.

Normally software talk to one serial port time but some
LayerScape platform require all the UART devices enabled
in Linux for various use case.

Adding support to probe all enabled serial devices like SBSA
compliant PL011 UART ports probe and initialization by firmware.

dm: core: Access device flags through functions

2021-01-05T19:24:41+00:00

At present flags are stored as part of the device. In preparation for
storing them separately, change the access to go through inline functions.

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25+00:00

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

common: rename getc() to getchar()

2020-10-22T13:54:53+00:00

The sandbox is built with the SDL2 library with invokes the X11 library
which in turn calls getc(). But getc() in glibc is defined as

    int getc(FILE *)

This does not match our definition.

    int getc(void)

The sandbox crashes when called with parameter -l.

Rename our library symbol getc() to getchar().

drivers: serial: Make serial_initialize return int

2020-08-06T18:27:27+00:00

serial_initialize is called only during the common init sequence, after
relocation (in common/board_r.c). Because it has a void return value, it
has to wrapped in initr_serial. In order to be able to get rid of this
indirection, make serial_initialize return int.

Remove extern from prototype in order to silence the following checkpatch
warning:
check: extern prototypes should be avoided in .h files

serial: Set baudrate on boot

2020-04-16T14:07:57+00:00

Currently, the baud rate is never set on boot. This works ok when a previous
bootloader has configured the baudrate properly, or when the baudrate is set to
a reasonable default in the serial driver's probe(). However, when this is not
the case, we could be using a different baud rate than what was configured.
