mach-snapdragon: generalise board support

2024-03-01T14:44:37+00:00

Historically, Qualcomm boards have relied on heavy hardcoding in U-Boot,
in many cases to the specific SoC but also to the board itself (e.g.
memory map). This has been largely resolved by modernising the Qualcomm
drivers in U-Boot, however the board code still largely follows this
model.

This patch removes the board specific memory maps and duplicated board
init code, replacing it with generic init code.

The memory map is now built at runtime based on data read from DT, this
allows for the memory map to be provided without having to recompile
U-Boot. Support is also added for booting with appended DTBs, so that
the first-stage bootloader can populate the memory map for us.

The sdm845 specific init code is dropped entirely, it set an environment
variable depending on if a button was pressed, but this variable wasn't
used in U-Boot, and could be written to use the button command instead.

The KASLR detection is also dropped as with appended dtb, the kaslr seed
can be read directly from the DTB passed to U-Boot.

A new qcom_defconfig is added, with the aim of providing a generic
U-Boot configuration that will work on as many Qualcomm boards as
possible. It replaces the defconfig files for the Dragonboard 845c,
Galaxy S9, and QCS404 EVB. For now the db410c and 820c are excluded as
they still have some board code left.

Similarly, the config headers for db845c, starqltechn, and qcs404-evb
are replaced by a single qcom header.

The previously db410c-specific board_usb_init() function is made to be
generic and is added to mach-snapdragon. While we lack proper modelling
for USB configuration, using a well-known named pinctrl state is a
reasonably generic middleground, and works using upstream DT. This
function will do nothing unless the USB node has a pinctrl state named
"device", in which case it will be set when entering USB peripheral
mode.

clk/qcom: use function pointers for enable and set_rate

2024-01-16T12:26:24+00:00

Currently, it isn't possible to build clock drivers for more than one
platform due to how the msm_enable() and msm_set_rate() callbacks are
implemented.

Extend qcom_clk_data to include function pointers for these and convert
all platforms to use them.

Previously, clock drivers relied on include/configs/ to include the
board specific sysmap header, however as most of the header contents are clock
driver related, import the contents directly into each clock driver and
remove the header. The only exception here is the dragonboard820c board file
which includes some pinctrl macros, those are also inlined.

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

Convert CONFIG_SYS_BOOTM_LEN to Kconfig

2022-07-07T18:01:09+00:00

This converts the following to Kconfig:
   CONFIG_SYS_BOOTM_LEN

As part of this, rework error handling in boot/bootm.c so that we pass
the buffer size to handle_decomp_error as CONFIG_SYS_BOOTM_LEN will not
be available to host tools but we do know the size that we passed to
malloc().
