The firmware running on the bcm2835 SoC's VideoCore CPU manages the
display controller. Add a simple "LCD" driver that communicates with the
firmware using the property mailbox protocol. This configures the
display and frame-buffer to match whatever physical resolution the
firmware chosen when booting, which is typically the native resolution
of the attached display device, presumably unless otherwise specified
in config.txt on the boot media.
Enable this driver in the Raspberry Pi board configuration.

The patch is a port from the framebuffer driver

on davinci da8xx and OMAP-L138 boards.
As base for the port, the following commit (last changes

mx3fb.c was based on CONFIG_LCD and is moved by this patch to
CONFIG_VIDEO, which has greater freedom in selecting videomodes
even at runtime.
This renders the accumulating list of display defines
(CONFIG_DISPLAY_VBEST..., CONFIG_DISPLAY_C057...) obsolete as
these may be setup through env variables:
uboot> setenv mydisplay 'video=ctfb❌240,y:320,depth:16,mode:0,pclk:185925,
le:9,ri:17,up:7,lo:10,hs:1,vs:1,sync:100663296,vmode:0'
uboot> setenv videomode ${mydisplay}
This commit also fixes the board config files for qong and
imx31_phycore boards as needed. The videomode settings of
previously supported displays are added to CONFIG_EXTRA_ENV_SETTINGS
now. CONFIG_SYS_MALLOC_LEN for imx31_phycore board is increased
to make the frame buffer allocation working with the changed
driver.

Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
