+Cross-compiling the GRUB
+========================
+
+GRUB defines 3 platforms:
+
+  - "Build" is the one which build systems runs on.
+  - "Host" is where you execute GRUB utils.
+  - "Target" is where GRUB itself runs.
+
+For grub-emu host and target must be the same but may differ from build.
+
+If build and host are different make check isn't available.
+
+If build and host are different man pages are not generated.
+
+As an example imagine you have a build system running on FreeBSD on sparc
+which prepares packages for developpers running amd64 GNU/Linux laptop and
+they need to make images for ARM board running U-boot. In this case:
+
+build=sparc64-freebsd
+host=amd64-linux-gnu
+target=arm-uboot
+
+For this example the configure line might look like (more details below)
+(some options are optional and included here for completeness but some rarely
+used options are omited):
+
+./configure BUILD_CC=gcc BUILD_FREETYPE=freetype-config --host=amd64-linux-gnu
+CC=amd64-linux-gnu-gcc CFLAGS="-g -O2" FREETYPE=amd64-linux-gnu-freetype-config
+--target=arm --with-platform=uboot TARGET_CC=arm-elf-gcc
+TARGET_CFLAGS="-Os -march=armv6" TARGET_CCASFLAGS="-march=armv6"
+TARGET_OBJCOPY="arm-elf-objcopy" TARGET_STRIP="arm-elf-strip"
+TARGET_NM=arm-elf-nm TARGET_RANLIB=arm-elf-ranlib LEX=gflex
+
+You need to use following options to specify tools and platforms. For minimum
+version look at prerequisites. All tools not mentioned in this section under
+corresponding platform are not needed for the platform in question.
+
+  - For build
+    1. BUILD_CC= to gcc able to compile for build. This is used, for
+       example, to compile build-gentrigtables which is then run to
+       generate sin and cos tables.
+    2. BUILD_CFLAGS= for C options for build.
+    3. BUILD_CPPFLAGS= for C preprocessor options for build.
+    4. BUILD_FREETYPE= for freetype-config for build (optional).
+
+  - For host
+    1. --host= to autoconf name of host.
+    2. CC= for gcc able to compile for host
+    3. CFLAGS= for C options for host.
+    4. CPPFLAGS= for C preprocessor options for host.
+    5. LDFLAGS= for linker options for host.
+    6. FREETYPE= for freetype-config for host (optional).
+    7. Libdevmapper if any must be in standard linker folders (-ldevmapper) (optional).
+    8. Libfuse if any must be in standard linker folders (-lfuse) (optional).
+    9. Libzfs if any must be in standard linker folders (-lzfs) (optional).
+    10. Liblzma if any must be in standard linker folders (-llzma) (optional).
+
+  - For target
+    1. --target= to autoconf cpu name of target.
+    2. --with-platform to choose firmware.
+    3. TARGET_CC= for gcc able to compile for target
+    4. TARGET_CFLAGS= for C options for target.
+    5. TARGET_CPPFLAGS= for C preprocessor options for target.
+    6. TARGET_CCASFLAGS= for assembler options for target.
+    7. TARGET_LDFLAGS= for linker options for target.
+    8. TARGET_OBJCOPY= for objcopy for target.
+    9. TARGET_STRIP= for strip for target.
+    10. TARGET_NM= for nm for target.
+    11. TARGET_RANLIB= for ranlib for target.
+
+  - Additionally for emu, for host and target.
+    1. SDL is looked for in stadard linker directories (-lSDL) (optional)
+    2. libpciaccess is looked for in stadard linker directories (-lpciaccess) (optional)
+    3. libusb is looked for in stadard linker directories (-lusb) (optional)
+
+  - Platform-agnostic tools and data.
+    1. make is the tool you execute after ./configure.
+    2. Bison is specified in YACC= variable
+    3. Flex is specified in LEX= variable
+    4. GNU unifont and Djvu sans are looked for in standard directories.

-In @file{~/.bazaar/bazaar.conf}, add "cia_send_revno = true". 
-Optionally, you can also add "cia_user = myusername" if you'd
-like CIA service to use a specific account (for statistical purpose).
+On emu stack and heap are just normal host OS stack and heap. Stack is typically
+8 MiB although it's OS-dependent.

-In the @file{.bzr/branch/branch.conf} of your checkout branch,
-"set nickname = /path_to_this_branch" and "cia_project = GNU GRUB".
+On i386-pc, i386-coreboot, i386-qemu and i386-multiboot the stack is 60KiB.
+All available space between 1MiB and 4GiB marks is part of heap.

-Additionally, please set cia_send_revno in the [DEFAULT] section
-of your @file{~/.bazaar/bazaar.conf}. E.g.:
+On *-xen stack is 4MiB. If compiled for x86-64 with GCC 4.4 or later adressable
+space is unlimited. When compiled for x86-64 with older GCC version adressable
+space is limited to 2GiB. When compiling for i386 adressable space is limited
+to 4GiB. All adressable pages except the ones for stack, GRUB binary, special
+pages and page table are in the heap.

-@example

-cia_send_revno = true

+On *-efi GRUB uses same stack as EFI. If compiled for x86-64 with GCC 4.4 or
+later adressable space is unlimited. When compiled for x86-64 with older GCC
+version adressable space is limited to 2GiB. For all other platforms adressable
+space is limited to 4GiB. GRUB allocates pages from EFI for its heap, at most
+1.6 GiB.

-Remember to install cia-clients (Debian/Ubuntu package) to be able to use CIA.
+On i386-ieee1275 and powerpc-ieee1275 GRUB uses same stack as IEEE1275.
+It allocates at most 32MiB for its heap.
+
+On sparc64-ieee1275 stack is 256KiB and heap is 2MiB.
+
+On mips(el)-qemu_mips and mipsel-loongson stack is 2MiB (everything below
+GRUB image) and everything above GRUB image (from 2MiB + kernel size)
+until 256MiB is part of heap.

+On mips-arc stack is 2MiB (everything below GRUB image) and everything above
