      MIPS: PowerTV: Fix support for timer interrupts with > 64 external IRQs · 010c108d
      David VomLehn authored
      The MIPS processor is limited to 64 external interrupt sources. Using a
      greater number without IRQ sharing requires reading platform-specific
      registers. On such platforms, reading the IntCtl register to determine
      which interrupt corresponds to a timer interrupt will not work.
      
      On MIPSR2 systems there is a solution - the TI bit in the Cause register,
      specifically indicates that a timer interrupt has occured. This patch uses
      that bit to detect interrupts for MIPSR2 processors, which may be expected
      to work regardless of how the timer interrupt may be routed in the hardware.

      MIPS: PowerTV: Streamline access to platform device registers · 59dfa2fc
      David VomLehn authored
      Pre-compute addresses for the basic ASIC registers. This speeds up access
      and allows memory for unused configurations to be freed. In addition,
      uninitialized register addresses will be returned as NULL to catch bad
      usage quickly.

      MIPS: Fix vmlinuz build for 32bit-only math shells · 9c4a6fce
      Alexander Clouter authored
      POSIX requires $((<expression>)) arithmetic in sh only to have long
      arithmetic so on 32-bit sh binaries might do only 32-bit arithmetic but
      the arithmetic done in arch/mips/boot/compressed/Makefile needs 64-bit.
      
      I play with the AR7 platform, so VMLINUX_LOAD_ADDRESS is
      0xffffffff94100000, and for an example 4MiB kernel
      VMLINUZ_LOAD_ADDRESS is made out to be:
      ----
      alex@berk:~$ bash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
      ffffffff94500000
      alex@berk:~$ dash -c 'printf "%x\n" $((0xffffffff94100000 + 0x400000))'
      80000000003fffff
      ----
      
      The former is obviously correct whilst the later breaks things royally.
      
      Fortunately working with only the lower 32bit's works for both bash and
      dash:
      ----
      $ bash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
      94500000
      $ dash -c 'printf "%x\n" $((0x94100000 + 0x400000))'
      94500000
      ----
      
      So, we can split the original 64bit string to two parts, and only
      calculate the low 32bit part, which is big enough (1GiB kernel sizes
      anyone?) for a normal Linux kernel image file, now, we calculate the
      VMLINUZ_LOAD_ADDRESS like this:
      
      1. if present, append top 32bit of VMLINUX_LOAD_ADDRESS" as a prefix
      2. get the sum of the low 32bit of VMLINUX_LOAD_ADDRESS + VMLINUX_SIZE
      
      This patch fixes vmlinuz kernel builds on systems where only a
      32bit-only math shell is available.
      
      Patch Changelog:
        Version 2
          - simplified method by using 'expr' for 'substr' and making it work
      	with dash once again
        Version 1
          - Revert the removals of '-n "$(VMLINUX_SIZE)"' to avoid the error
              of "make clean"
          - Consider more cases of the VMLINUX_LOAD_ADDRESS
        Version 0
          - initial release
