Hi all,

I just tagged and pushed skiboot-5.4.1. release notes:


skiboot-5.4.1 was released on Tuesday November 29th 2016. It replaces
skiboot-5.4.0 as the current stable release.

Over skiboot-5.4.0, we have a few changes:

- Nuvoton i2c TPM driver: bug fixes and improvements, especially around
  timeouts and error handling.
- Limit number of “Poller recursion detected” errors to display. In some
  error conditions, we could spiral out of control on this and spend all
  of our time printing the exact same backtrace.
- slw: do SLW timer testing while holding xscom lock. In some situations
  without this, it could take long enough to get the xscom lock that the
  1ms timeout would expire and we’d falsely think the SLW timer didn’t
  work when in fact it did.
- p8i2c: Use calculated poll_interval when booting OPAL. Otherwise we’d
  default to 2seconds (TIMER_POLL) during boot on chips with a
  functional i2c interrupt, leading to slow i2c during boot (or hitting
  timeouts instead).
- i2c: More efficiently run TPM I2C operations during boot, avoiding
  hitting timeouts
- fsp: Don’t recurse pollers in ibm_fsp_terminate
