Wish page for a mediawiki extension to make easy editing and generate pretty register descriptions, together with the possibility of export in a machine friendly format.

disadvantages

Someone has to write it, be a maintainer.

alternatives

  • Use mediawiki templates.
    Have two forms of arguments named/unnamed(indexed by number). Named arguments strip the start and end spaces. Unnamed, the '=' character transform in a named argument.
  • Scribunto - embed lua scripting
    Page => Template => Module. Uses the same argument parsing rules as templates, with the same limitations.

format

Should be easy to edit, should be easy to write the extension's parser.

SRAM_CTL0_CFG

30 0
SRAM_C1_MAP
Offset
0x0000
Name Bits R/W Default Values Description
SRAM_C1_MAP 30:0
RW
0x7fffffff
 0 = CPU/DMA
 1 = VE
Each bit represents a page to be mapped to the CPU/DMA unit or to the VE. Each bit (combination) may represent a byte/page of sram C1
