Do this to reduce indentation a bit. Also it may be desireable
to group GPIO configuration such that some GPIOs are handled
outside program_gpios() call and would not be included in

84439c26d8 soc/amd/picasso/psp: move soc_get_mbox_address to common PSP gen2 code
The function to get the PSP mailbox address is the same on Picasso and
Cezanne, so move it to the common PSP generation 2 code. The function is
only used in the same compilation unit, but it can't be marked as static
due to the function prototype in amdblocks/psp.h that is still needed
for Stoneyridge.

0ad97332e4 soc/amd/piasso/uart: move get_uart_base prototype to common code header
This will result in less code duplication when the common AMD SoC UART
support gets used for more AMD SoCs.

e7382991ab soc/amd/common/uart: move CONSOLE_UART_BASE_ADDRESS back to SoC code
This partially reverts commit 6f8f9c969b
by moving CONSOLE_UART_BASE_ADDRESS back to the SoC-specific code, since
the number and base addresses of UARTs turned out to be rather SoC-
specific. The help text for the AMD_SOC_CONSOLE_UART option also
contained those base addresses, so remove that as well.

b82cafad93 soc/amd/picasso: remove broken and unused legacy UART support
The UARTs in the Picasso SoC are memory mapped, but there is also some
hardware support that isn't used by any board to make the UARTs behave
like the ones found on legacy x86 machines from the 90s.

In the MMIO mode the MMIO address of the UART controller is passed to
the OS via ACPI. The OS expects the base clock of the UART controller to
be 48MHz (see the cz_uart_desc struct in drivers/acpi/acpi_apd.c and
drivers/tty/serial/8250/8250_dw.c in the Linux kernel) in this case. It
is also possible to enable additional decodes from four 8 byte legacy
I/O locations used for serial ports to the different UART controllers,
which doesn't disable the MMIO access though. The legacy I/O-mapped
serial ports are usually expected to have a base clock of 16*115200Hz
which the hardware can also provide to the UART's baud rate generator.
So there are two possible valid configurations to use the UARTs; either
MMIO access in combination with a 48MHz base clock or the legacy I/O
decode with a ~1.8MHz base clock.

The existing code unconditionally generates ACPI objects for all enabled
UARTs, so those shouldn't be put into legacy mode and switching the base
clock to ~1.8MHz was only done in the case that the UART was used as
coreboot console UART which still used the MMIO access, but the lower
base clock. Since no board even selects this option and it's rather
invasive to properly implement this feature, just drop the corresponding
broken code.

TEST=SoC UART console still works on Mandolin.

Allocation now happens prior to device enumeration. The
step cbmem_add() is a no-op here, if reached for some

harmful with followup works, as it would wipe out the
CBMEM console and ChromeOS related fields without them
being set again.

7522a8fe0f arch/x86: Move prologue to .init section
For arch/x86 the realmode part has to be located within the same 64
KiB as the reset vector. Some older intel platforms also require 4 KiB
alignment for _start16bit.

To enforce the above, and to separate required parts of .text without
matching *(.text.*) rules in linker scripts, tag the pre-C environment
assembly code with section .init directive.

Description of .init section for ELF:

This section holds executable instructions that contribute to the
process initialization code. When a program starts to run, the
system arranges to execute the code in this section before calling the
main program entry point (called main for C programs).
