Each bus now has two definitions for each DIMM slot. If populated with a DDR5 DIMM, the SPD Hub device will be used to gather temperature readings. If populated with an NVDIMM, we'll only need to talk to the controller sitting behind the hub (local device type 1011b), to read temperature and use the FW mailbox. This also removes some logic in the I3C driver which restricts use of certain addresses due to signal integrity paranoia. An NVDIMM controller in slot 6 of any bus is blocked by this logic, and unfortunately we don't have any control over the static address scheme used on the SPD bus, so the restriction must be removed. Tested: Probed I3C busses successfully with DIMMs installed in busses 0 and 1: $ gpioset $(gpiofind FM_SPD_SWITCH_CTRL_N)=1 $ echo 1e7a2000.i3c0 > /sys/bus/platform/drivers/dw-i3c-master/bind $ echo 1e7a3000.i3c1 > /sys/bus/platform/drivers/dw-i3c-master/bind $ ls /dev/i3c* /dev/i3c-0-3c000000000 /dev/i3c-0-3c000000001 /dev/i3c-0-3c000000002 /dev/i3c-0-3c000000003 /dev/i3c-0-3c000000004 /dev/i3c-0-3c000000005 /dev/i3c-0-3c000000006 /dev/i3c-0-3c000000007 /dev/i3c-0-3c000000008 /dev/i3c-0-3c000000009 /dev/i3c-0-3c00000000a /dev/i3c-0-3c00000000b /dev/i3c-0-3c00000000c /dev/i3c-0-3c00000000d /dev/i3c-0-3c00000000e /dev/i3c-1-3c000000000 /dev/i3c-1-3c000000001 /dev/i3c-1-3c000000002 /dev/i3c-1-3c000000003 /dev/i3c-1-3c000000004 /dev/i3c-1-3c000000005 /dev/i3c-1-3c000000006 /dev/i3c-1-3c000000007 /dev/i3c-1-3c000000008 /dev/i3c-1-3c000000009 /dev/i3c-1-3c00000000a /dev/i3c-1-3c00000000b /dev/i3c-1-3c00000000c /dev/i3c-1-3c00000000d /dev/i3c-1-3c00000000e Change-Id: I016450edad1ed4ec981500f04122976f1647b8ee Signed-off-by: Jonathan Doman <jonathan.doman@intel.com> 2021-10-19T22:10:38+00:00 Jae Hyun Yoo jae.hyun.yoo@intel.com 2021-03-09T22:01:00+00:00 urn:sha1:be338dfd47ee3976bd1a1ebcb5f0555b330512a1 Modified the Aspeed global driver as a platform driver instead of a postcore initialized one to make it get a reset control resource properly while probing the module. To make it probed ahead of bus modules, it also modifies the object order in makefile.

It allows to use simulation software like QEMU where I3C may not be implemented and all its registers are set to zeros.
