[U-Boot] [PATCH 00/70 V2] serial: Massive rework of the serial subsystem

Marek Vasut
2012-09-29T00:30:17Z

This patchset is a STAGE 1 of preparation of the stdio and serial subsys
for the driver model.

The idea of this patchset is:

1) Clean up the struct serial_device
Do a coding style cleanup.
2) Replace .init and .uninit with .start and .stop
This is to bring struct serial_device much closer to struct stdio_dev
so later on, these structures can be overlayed and struct serial_device
can be easily passed to stdio subsystem directly.
3) Do minor cleanups on the PXA and MPC512X
Basically for PXA this means to remove default_serial_console() call
from every single PXA board and move it into PXA serial driver. For
MPC512X, that means properly defining PSC console number.
4) Add support for CONFIG_SERIAL_MULTI into every single driver
Implement support for both non-multi and multi operation into every
single serial driver in the U-Boot source tree. This is a vast majority
of this patchset.
5) Unconditionally enable CONFIG_SERIAL_MULTI
Enable the multi operation throughout the whole U-Boot tree, both for
SPL and non-SPL builds. There was also some breakage due to this, so
this patchset also addresses that with minor fixes.
6) Remove unused code used for the non-multi operation
Remove code that was used when CONFIG_SERIAL_MULTI was not selected.
Also remove all occurances of CONFIG_SERIAL_MULTI throughout the source
tree. Some parts of the code must have been adjusted to cope with this
since they were initially only written for non-multi operation. These
were minor adjustments mostly in macros though.

This changeset obviously does mean size growth of U-Boot, therefore some
statistics (stock U-Boot first, patchset last):
