u-boot: new recipe

This may become useful for the ARM port if we want something like
writembr to include an u-boot image to put on install media. Until then,
haikuports is just a convenient way to store my patches.

+Subject: Quirk to ignore invalid video mode

+My TV has an invalid video mode in its EDID data, using it results in

+SUMMARY="Boot loader for embedded boards"
+DESCRIPTION="boot loader for embedded boards based on PowerPC, ARM, MIPS and several other \
+processors, which can be installed in a boot ROM and used to \
+initialize and test the hardware or to download and run application code.
+
+The development of U-Boot is closely related to Linux: some parts of \
+the source code originate in the Linux source tree, we have some \
+header files in common, and special provision has been made to \
+support booting of Linux images.
+
+Some attention has been paid to make this software easily \
+configurable and extendable. For instance, all monitor commands are \
+implemented with the same call interface, so that it's very easy to \
+add new commands. Also, instead of permanently adding rarely used \
+code (for instance hardware test utilities) to the monitor, you can \
+load and run it dynamically."
