dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46+00:00

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

x86: serial: Add a coreboot serial driver

2020-02-03T17:19:25+00:00

Coreboot can provide information about the serial device in use on a
platform. Add a driver that uses this information to produce a working
UART.

serial: ns16550: Support run-time configuration

2020-02-03T17:19:13+00:00

At present this driver uses an assortment of CONFIG options to control
how it accesses the hardware. This is painful for platforms that are
supposed to be controlled by a device tree or a previous-stage bootloader.

Add a new CONFIG option to enable fully dynamic configuration. This
controls register spacing, size, offset and endianness.

serial: ns16550: Use old baud rate divisor for flushing if not given

2020-01-24T16:19:52+00:00

If baud_divisor is not set (i.e. == -1), we should use the baud divisor
already in use for flushing the xmit register. If we don't flush the
xmit register, then SPL will hang.

common: Move hang() to the same header as panic()

2020-01-17T22:53:40+00:00

At present panic() is in the vsprintf.h header file. That does not seem
like an obvious choice for hang(), even though it relates to panic(). So
let's put hang() in its own header.

common: Move clock functions into a new file

2020-01-17T18:27:29+00:00

These three clock functions don't use driver model and should be migrated.
In the meantime, create a new file to hold them.

common: Drop floppy disk support

2020-01-17T18:26:50+00:00

This seems pretty old now. It has not been converted to driver model and
is not used by any boards.

Drop it.
