The help text for the AMD_SOC_CONSOLE_UART option also contained those base addresses, so remove that as well.

2021-01-14soc/amd/picasso: remove broken and unused legacy UART supportFelix Held
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.

2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
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).

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-08-24mrc_cache: Add mrc_cache fetch functions to support non-x86 platformsShelley Chen
Create two new functions to fetch mrc_cache data (replacing mrc_cache_get_current): - mrc_cache_load_current: fetches the mrc_cache data and drops it into the given buffer. This is useful for ARM platforms where the mmap operation is very expensive. - mrc_cache_mmap_leak: fetch the mrc_cache data and puts it into a given buffer. This is useful for platforms where the mmap operation is a no-op (like x86 platforms). As the name mentions, we are not freeing the memory that we allocated with the mmap, so it is the caller's responsibility to do so. Additionally, we are replacing mrc_cache_latest with mrc_cache_get_latest_slot_info, which does not check the validity of the data when retrieving the current mrc_cache slot. This allows the caller some flexibility in deciding where they want the mrc_cache data stored (either in an mmaped region or at a given address).

2020-08-21soc/amd/common: add rudimentary ATIF supportAaron Durbin
The Linux kenerl driver for AMD gpu currently has a floor value of 12 for brightness settings (AMDGPU_DM_DEFAULT_MIN_BACKLIGHT). AMD indicates they did this because they were concerned with certain panels flickering at lower backlight values. However, for unaffected panels it's desirable to be able to have the panel "turn off" at the lowest backlight setting. The only way to do that is to provide ATIF bindings that indicate backlight range. Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full range for the backlight setting. If needed, this path can be built upon for fuller support, but for the time being this is the only thing necessary to make the backlight be full range.

2020-07-27soc/amd/common: Move spi access functions into their own fileMartin Roth
Because there was a lot of discussion about the size increase, I also looked at the impact of calling the get_spi_bar() function vs reading spi_base directly and just not worring about whether or not spi_base was already set. Using the spi_base variable directly is 77 bytes bytes for all 6 functions. it's roughly double the size to call the function at 153 bytes. This was almost entirely due to setting up a call stack. If we add an assert into each function to make sure that the spi_base variable is set, it doubles from the size of the function call to 333 bytes. For my money, the function call is the best bet, because it not only protects us from using spi_base before it's set, it also gets the value for us (at least on x86, on the PSP, it still just dies.)
