Commit c3e2ee65 ("MIPS: generic: Add support for zboot") added support for self-extracting images to Generic MIPS. However, the intended way to boot Generic MIPS kernels is using FIT Images and UHI boot protocol, but currently there's no way to make self-extracting FIT Image (only legacy uzImages). Add a target for this named "vmlinuz.itb", which will consist of vmlinuz.bin and selected DT blobs. It will allow to have the advantages of both UHI and self-extracting images. Signed-off-by:

1. All final targets like vmlinuz.{bin,ecoff,srec} etc. should reside in $(objtree)/arch/mips/boot, not in the root $(objtree) directory. The only file that should be left there is vmlinuz, similar to other architectures. 2. Add all the targets to $(targets) variable, so they'll be properly accounted by Kbuild. This also allows to remove redundant $(clean-files) (which were missing uzImage BTW). 3. Prefix all targets with $(obj)/$(objtree), depending on their locations. Misc: fix the identation of the 'STRIP' quiet message. Signed-off-by: -

Ocelot belongs to a family of SoC named the VCore III. In order to add these new Soc, use the new symbol SOC_VCOREIII instead of a one dedicated to Ocelot.

In play_dead function, the whole 64-bit PC mailbox was used as a indicator to determine if the master core had written boot jump information. However, after we introduced CSR mailsend, the hardware will not guarante an atomic write for the 64-bit PC mailbox. Thus we have to use the lower 32-bit which is written at the last as the jump indicator instead. Signed-off-by:

Tiezhu Yang authored
Add /sys/firmware/lefi/boardinfo to get mainboard and BIOS info easily on the Loongson platform, this is useful to point out the current used mainboard type and BIOS version when there exists problems related with hardware or firmware. The related structures are already defined in the interface specification about firmware and kernel which are common requirement and specific for Loongson64, so only add a new boardinfo.c file in arch/mips/loongson64. E.g. with this patch: [loongson@linux ~]$ cat /sys/firmware/lefi/boardinfo Board Info Manufacturer : LEMOTE Board Name : LEMOTE-LS3A4000-7A1000-1w-V01-pc Family : LOONGSON3 BIOS Info Vendor : Kunlun Version : Kunlun-A1901-V4.1.3-20200414093938 ROM Size : 4 KB Release Date : 2020-04-14 By the way, using dmidecode command can get the similar info if there exists SMBIOS in firmware, but the fact is that there is no SMBIOS on some machines, we can see nothing when execute dmidecode, like this: [root@linux loongson]# dmidecode # dmidecode 2.12 # No SMBIOS nor DMI entry point found, sorry.

Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.
