Fix stdout-path handling

Kconfig: make TPL_DM_SERIAL depend on TPL_DM

2019-12-03T13:43:23+00:00

This missing dependency seems like an oversight, since all other
TPL_DM_* options have it.

serial: usb: Correct the usbtty_...() prototypes

2019-12-02T23:23:10+00:00

The function declarations in serial.h are not in sync with what is
currently used in usbtty. Fix this by updating the header and including
it, to help catch future such problems.

dm: serial: Handle "stdout-path" with ":options" correctly

2019-12-02T23:18:05+00:00

With commit f0921f5098d8 ("fdt: Sync up to the latest libfdt"),
SiFive Unleashed board does not boot any more. This was due to
the U-Boot local changes commit 77d7fff8cec2 ("fdt: Fix handling
of paths with options in them") to libfdt/fdt_ro.c was dropped
during the libfdt upgrade.

>From the history [1] it was mentioned that the U-Boot changes
commit 77d7fff8cec2 ("fdt: Fix handling of paths with options in
them") was rejected by libfdt upstream, hence we need find another
way to fix the things.

This commit uses another method, by updating serial_check_stdout()
directly to handle the situation of "stdout-path" with ":options".
A simpler way is to change the logic in fdtdec_get_chosen_node()
to do similar thing, but I feel that not every property in chosen
node may have the option in them, hence it would make more sense
to do the special handling in serial_check_stdout() directly.

drivers: bcm283x: Set pre-location flag for OF_BOARD

2019-11-24T09:46:27+00:00

U-Boot support on Raspberry Pi 4 relies on the device-tree
provided by the firmware. The blob does not contain the
U-Boot specific pre-loc-rel properties. The result is, that
the U-Boot banner is not printed.

We fix this by setting the DM_FLAG_PRE_RELOC flag in the driver,
if we rely on a device-tree provided by the firmware.

serial: serial_mtk: add non-DM version for SPL

2019-10-25T15:20:43+00:00

This patch adds non-DM version for mtk hsuart driver and makes it
compatible with ns16550a driver in configuration.
This is needed in SPL with CONFIG_SPL_DM disabled for reducing size.

dm: pci: Add a function to read a PCI BAR

2019-10-08T05:57:43+00:00

At present PCI address transaction is not supported so drivers must
manually read the correct BAR after reading the device tree info. The
ns16550 has a suitable implementation, so move this code into the core
DM support.

Note that there is no live-tree equivalent at present.
