* MIPS: Add support for vmlinuz.bin appended dtbJonas Gorski2015-06-212-1/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for detecting a vmlinuz.bin appended dtb and overriding the boot arguments to match the UHI interface. To ensure _edata / __apendend_dtb points to the actual end of the binary, align the data section to 16 bytes instead of the address cursor. Due to ld.script not going through the preprocessor, we can't check for MIPS_ZBOOT_APPENDED_DTB being enabled, so always reserve space for it. It should have no consequences for booting without it enabled except 1 MiB more ram usage during the uncompressing stage.

* MIPS: Loongson: Naming style cleanup and reworkHuacai Chen2015-06-211-1/+1
| | | | | | | | | | | | | | | | | | | | Currently, code of Loongson-2/3 is under loongson directory and code of Loongson-1 is under loongson1 directory. Besides, there are Kconfig options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is very ugly and confusing. Since Loongson-2/3 are both 64-bit general- purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

* MIPS: Add uImage build targetJames Hogan2013-09-032-0/+16
| | | | | | | | | | | | | | | | | | | Add a uImage build target for MIPS, which builds uImage.gz (a U-Boot image of vmlinux.bin.gz), and then symlinks it to uImage. This allows for the use of other compression algorithms in future, and is how a few other architectures do it. It's enabled conditionally on load-y >= 0xffffffff80000000 which hopefully allows 64bit kernels to also work as long as the load and entry address can be represented by the 32bit addresses in the U-Boot image format.

| | | | | | | | | | | | | | | | | | | | | | | | | | The vmlinux load address and entry address is calculated in multiple places: - arch/mips/Makefile defines load-y from CONFIG_PHYSICAL_START (or defined by the platform) and passes it to arch/mips/boot/compressed/Makefile. - arch/mips/boot/compressed/Makefile calculates kernel entry using nm. - arch/mips/lasat/image/Makefile calculates both load and entry address using nm. Lets combine these in the main Makefile and then pass them as Make parameters to each of the three boot image Makefiles (in boot/, boot/compressed, lasat/image/). The boot/ Makefile doesn't currently use them, but will soon need to for U-Boot image targets. The existing load-y definition is used in preference to calculating the load address using nm.

See commit c58299a (kbuild: create an "include chroot" for DT bindings) merged in v3.10-rc1 for details. MIPS structures it's dts files a little differently to other architectures, having a separate dts directory for each SoC/platform, but most of the definitions in the dt-bindings/ directory are common so for now lets just have a single "include chroot" for all MIPS platforms.
