When U-Boot is enabled and no custom patch directory has been set,
then the current test:
ifneq ($(strip $(BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR)),"")
works. However, when U-Boot is not enabled, but still gets compiled
because mkimage is needed to build the kernel,
BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR is completely empty. It does not
even have quotes. So the test in fact needs to be:
ifneq ($(call qstrip,$(BR2_TARGET_UBOOT_CUSTOM_PATCH_DIR)),)

Marvell boards like the sheevaplug needs a special .kwb image format,
so add an option for it similar to how we handle zImage/uImage/..
for the kernel.

Now that TARGET_CC contains several space-separated words, it must be

A few minor modifications of u-boot.mk is needed to support 2010.06:
- U-Boot now uses ARCH=powerpc like the kernel (instead of ARCH=ppc)
- Library files have moved, so adjust the target mkimage/fw_printenv rules
(still compatible with older versions)

The first patch allows to build with an EABI toolchain. The second
patch disables the install step of at91dataflashboot Makefile since it
tries to copy files to /tftpboot.

Use AT91BOOTSTRAP_BOARD instead of BOARD_NAME. Remove
AT91BOOTSTRAP_VERSION from the final binary image name.

At the same time, remove the unused AT91BOOTSTRAP_PATCH_LEVEL and
AT91BOOTSTRAP_PATCHED_VERSION variables.

The boot source configuration options were depending on U-Boot
configuration options. Let's make it independent and just allow the
user to select whichever boot source is appropriate.

The build process of grub2 breaks the compilation. It breaks with:
./configure: line 4766: syntax error near unexpected token `external'
./configure: line 4766: `AM_GNU_GETTEXT(external)'
In addition to this, it later requires Ruby. Do we really want to make
Buildroot depend on Ruby being installed on the host ? Do we really
want to build our own Ruby ? Do we even care about Grub2 ?

Much of the grub2.mk seems to have been copy/pasted from

grub2 now builds fine, but some work remains to make it usable. What

installation procedure and what should Buildroot do ?

grub can already only be selected for x86 and x86_64. No need to check
again for this in grub.mk.

The bootloader being very specific to the hardware, being able to
build U-Boot from an arbitrary tarball available on the web might be
needed.
Therefore, for U-Boot, we provide two methods :
* Get a given stable version from U-Boot official FTP server
* Get an arbitrary tarball
This should hopefully satisfy most needs, without complicating too
much the U-Boot build procedure on Buildroot side.

Remove all the bootsource selection mechanism and the horribly
complicated BR2_TARGET_UBOOT_DEFAULT_ENV thing, which wanted to be
generic, but was in fact very AT91-specific.
Just keep things simple: we build U-Boot with the board configuration
file specified in BR2_TARGET_UBOOT_BOARDNAME.

To build mkimage for the host (which is needed to build an uImage of
the kernel), it is not necessary to configure U-Boot, and therefore to
have a particular board selected.
Therefore, this commit:
* Adds a verification at U-Boot configure step that a U-Boot board
name has been defined
* Sets a default U-Boot version if none has been specified, so that
even when U-Boot isn't selected but we want to build mkimage for
the host, a particular U-Boot version is picked.
* Make the host mkimage target depend only on U-Boot being
downloaded/extracted/patched, and the target mkimage/fw_printenv
targets depend on U-Boot being fully configured.
