SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one.

MIPS: remove dead code from asm/u-boot-mips.h Those wrappers for linker symbols were once used in the MIPS specific board.c implementation. Since the migration to generic board.c, those wrappers are dead code and can be removed.

MIPS: add handling for generic and EJTAG exceptions Add exception handlers for generic and EJTAG exceptions. Most of the assembly code is imported from Linux kernel and adapted to U-Boot. The exception vector table will be reserved above the stack before U-Boot is relocated. The exception handlers will be installed and activated after relocation in the initr_traps hook function. Generic exceptions are handled by showing a CPU register dump similar to Linux kernel. For example: malta # md 1 00000001: Ooops: $ 0 : 00000000 00000000 00000009 00000004 $ 4 : 8ff7e108 00000000 0000003a 00000000 $ 8 : 00000008 00000001 8ff7cd18 00000004 $12 : 00000002 00000000 00000005 0000003a $16 : 00000004 00000040 00000001 00000001 $20 : 00000000 8fff53c0 00000008 00000004 $24 : ffffffff 8ffdea44 $28 : 90001650 8ff7cd00 00000004 8ffe6818 Hi : 00000000 Lo : 00000004 epc : 8ffe6848 (text bfc28848) ra : 8ffe6818 (text bfc28818) Status: 00000006 Cause : 00000410 (ExcCode 04) BadVA : 8ff9e928 PrId : 00019300 ### ERROR ### Please RESET the board ### EJTAG exceptions are checked for SDBBP and delegated to the SDBBP handler if necessary. Otherwise the debug mode will simply be exited. The SDBBP handler currently prints the contents of registers c0_depc and c0_debug. This could be extended in the future to handle semi-hosting according to the MIPS UHI specification.

mips: add support to restore exception vector base before booting linux In U-Boot the exception vector base will be moved to top of memory, to be used to display register dump when exception occurs. But some old linux kernel does not honor the base set in CP0_EBASE. A modified exception vector base will cause kernel crash. This patch adds an option to enable reset exception vector base to its previous value, or a user configured value before booting linux kernel.
