[Skiboot] [PATCH v2 0/8] Add attention support for BMC based machine

[Vasant Hegde]

This patchset adds attention support for BMC based machine. With this
during abort/assert we will be able to log eSEL event with OPAL backtrace
and trigger host reboot.

This patchset introduces attention support for BMC based machine.
Patch 1-6 does various fixes to SEL code and does ipmi_msg pre-allocation.
Patch 6-7 take care of moving FSP specific code, adding platform hook etc.
Patch 8 implements attention support for BMC based machine.

Changes in v2:
  - Fixed corner case IPMI eSEL bug
  - Removed redundant memory allocation in eSEL code path
  - Preallocated ipmi_msg for PANIC event
  - Created ti_buffer and bt_buf as global variable instead of local

Vasant Hegde (8):
  IPMI: Fix corner case eSEL logging issue
  IPMI: Insert SEL event to IPMI queue head
  IPMI: Avoid unnecessary ipmi_msg allocation
  IPMI: Pre-allocate memory for PANIC event
  IPMI: Move MAX_PEL_SIZE to ipmi.h
  Move FSP specific abort() code to platform layer
