[PATCH v1 0/4] semihosting read console support

[Alex Bennée]

Hi,

This series introduces a new "blocking" console read function for
semihosting and plumbs it in to the ARM semihosting code. The main bit
of work is Keith's patch (with a few tweaks by me). The other
preparatory patches make sure the PC is updated after semihosting
succeeds and a little bit of clean-up.

The following patches need review
   01 - target arm remove unused EXCP_SEMIHOST leg
   02 - target arm only update pc after semihosting compl
   04 - tests tcg add a dumb as bricks semihosting consol

Alex Bennée (3):
  target/arm: remove unused EXCP_SEMIHOST leg
  target/arm: only update pc after semihosting completes
  tests/tcg: add a dumb-as-bricks semihosting console test

Keith Packard (1):
  semihosting: add qemu_semihosting_console_inc for SYS_READC
