/* The coreboot table information is for conveying information
* from the firmware to the loaded OS image. Primarily this
* is expected to be information that cannot be discovered by
* other means, such as querying the hardware directly.
*
* All of the information should be Position Independent Data.
* That is it should be safe to relocated any of the information
* without it's meaning/correctness changing. For table that
* can reasonably be used on multiple architectures the data
* size should be fixed. This should ease the transition between
* 32 bit and 64 bit architectures etc.
*
* The completeness test for the information in this table is:
* - Can all of the hardware be detected?
* - Are the per motherboard constants available?
* - Is there enough to allow a kernel to run that was written before
* a particular motherboard is constructed? (Assuming the kernel
* has drivers for all of the hardware but it does not have
* assumptions on how the hardware is connected together).
*
* With this test it should be straight forward to determine if a
* table entry is required or not. This should remove much of the
* long term compatibility burden as table entries which are
* irrelevant or have been replaced by better alternatives may be
* dropped. Of course it is polite and expedite to include extra

/**
* coreboot framebuffer
*
* The coreboot framebuffer uses a very common format usually referred
* to as "linear framebuffer":
*
* The first pixel of the framebuffer is the upper left corner, its
* address is given by `physical_address`.
*
* Each pixel is represented by exactly `bits_per_pixel` bits. If a
* pixel (or a color component therein) doesn't fill a whole byte or
* doesn't start on a byte boundary, it starts at the least signifi-
* cant bit not occupied by the previous pixel (or color component).
* Pixels (or color components) that span multiple bytes always start
* in the byte with the lowest address.
*
* The framebuffer provides a visible rectangle of `x_resolution` *
* `y_resolution` pixels. However, the lines always start at a byte
* boundary given by `bytes_per_line`, which may leave a gap after
* each line of pixels. Thus, the data for a pixel with the coordi-
* nates (x, y) from the upper left corner always starts at
*
* physical_address + y * bytes_per_line + x * bits_per_pixel / 8
*
* `bytes_per_line` is always big enough to hold `x_resolution`
* pixels. It can, however, be arbitrarily higher (e.g. to fulfill
* hardware constraints or for optimization purposes). The size of
* the framebuffer is always `y_resolution * bytes_per_line`.
*
* The coreboot framebuffer only supports RGB color formats. The
* position and size of each color component are specified indivi-
* dually by <color>_mask_pos and <color>_mask_size. To allow byte
* or word aligned pixels, a fourth (padding) component may be
* specified by `reserved_mask_pos` and `reserved_mask_size`.
*
* Software utilizing the coreboot framebuffer shall consider all
* fields described above. It may, however, only implement a subset
* of the possible color formats.
