skiboot 5.9.9 was released on Monday May 28th, 2018. It replaces
*skiboot-5.9.8* as the current stable release in the 5.9.x series.
Over *skiboot-5.9.8*, we have two bug fixes and a build fix, they are:
* OPAL_PCI_SET_POWER_STATE: fix locking in error paths
Otherwise we could exit OPAL holding locks, potentially leading to
all sorts of problems later on.
* lpc: Clear pending IRQs at boot
When we come in from hostboot the LPC master has the bus reset
indicator set. This error isn't handled until the host kernel
unmasks interrupts, at which point we get the following suprious
[ 20.053560375,3] LPC: Got LPC reset on chip 0x0 !
[ 20.053564560,3] LPC: Unknown LPC error Error address reg: 0x00000000
Fix this by clearing the various error bits in the LPC status
register before we initalise the skiboot LPC bus driver.
* stb: Build fixes in constructing secure and trusted boot header
