* Write boot progress to LPC ports 81 and 82Stewart Smith2019-04-241-2/+24
| | | | | | | | | | | There's a thought to write more extensive boot progress codes to LPC ports 81 and 82 to supplement/replace any reliance on port 80. We want to still emit port 80 for platforms like Zaius and Barreleye that have the physical display. Ports 81 and 82 can be monitored by a BMC though.

* Write boot progress to LPC port 80hStewart Smith2019-04-242-1/+91
| | | | | | | | | | | | | | | | | This is an adaptation of what we currently do for op_display() on FSP machines, inventing an encoding for what we can write into the single byte at LPC port 80h. Port 80h is often used on x86 systems to indicate boot progress/status and dates back a decent amount of time. Since a byte isn't exactly very expressive for everything that can go on (and wrong) during boot, it's all about compromise. Some systems (such as Zaius/Barreleye G2) have a physical dual 7 segment display that display these codes. So far, this has only been driven by hostboot (see hostboot commit 90ec2e65314c).

* hw/phys_map: Use GCIDs as a chip indexOliver O'Halloran2017-06-161-5/+5
| | | | | | | | | | | | | | Currently we pass in a proc_chip structure to phys_map_get(). All we we really need from this structure is the Global Chip ID (GCID). This patch reworks the function so that we only need to pass the GCID which allows us to use it before the proc_chip structures have been initialised (i.e in the HDAT parser).

* phys map: Add tests for holes in MMIO region and orderMichael Neuling2017-05-161-1/+27
| | | | | | | | This adds a couple of tests to ensure that there are no holes in the map for MMIO mappings and the map is sorted by start address. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
* Add tests for physical memory mapMichael Neuling2017-05-102-0/+178
This adds a bunch of tests to the physical memory map infrastructure. It checks for overlaps and alignment.. Signed-off-by: Michael Neuling <mikey@neuling.org> Signed-off-by: Stewart Smith <stewart@linux.vnet.ibm.com>
