[U-Boot] [PATCH 1/3] video: Add information about using TrueType fonts

[Simon Glass]

U-Boot supports using TrueType fonts on the console, which is useful for
presenting a nice UI to users, e.g. for system recovery.

Add information about how to compile this on ARM platforms, since this is
not obvious.

 For example to always use the hdmi connector, even if no cable is inserted,
 using edid info when available and otherwise initalizing it at 1024x768 at 60Hz,
 use: "setenv video-mode sunxi:1024x768-24 at 60,monitor=dvi,hpd=0,edid=1".

+TrueType fonts
+--------------
+
+U-Boot supports the use of antialiased TrueType fonts on some platforms. This
+has been tested in x86, ARMv7 and sandbox.
+
+To enable this, select CONFIG_CONSOLE_TRUETYPE. You can choose between several
+fonts, with CONSOLE_TRUETYPE_NIMBUS being the default.
+
+TrueType supports requires floating point at present. On ARMv7 platforms you
+need to disable use of the private libgcc. You can do this by disabling
+CONFIG_USE_PRIVATE_LIBGCC. See chromebook_jerry for an example. Note that this
+increases U-Boot's size by about 70KB at present.
+
+On ARM you should also make sure your toolchain supports hardfp. This is
+normally given in the name of your toolchain, e.g. arm-linux-gnueabihf (hf
+means hardware floating point). You can also run gcc with -v to see if it has
+this option.

[U-Boot] [PATCH 2/3] video: Add a default TrueType font

[Simon Glass]

At present it is possible to enable TrueType support but not include any
fonts. This results in a blank display. Select Nimbus as the default font
to avoid this.

[Simon Glass]

As an example of how to enable TrueType fonts, move chromebook_jerry over
to use these.
