drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)
This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
v2: add s/r support, fix Kconfig.

drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)
This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
v2: add s/r support, fix Kconfig.

V1:
When AST2500 acts as stand-alone VGA so that DRAM and DVO initialization
have to be achieved by VGA driver with P2A (PCI to AHB) enabling.
However, HW suggests disable Fast reset mode after DRAM initializaton,
because fast reset mode is mainly designed for ARM ICE debugger.
Once Fast reset is checked as enabling, WDT (Watch Dog Timer) should be
first enabled to avoid system deadlock before disable fast reset mode.
V2:
Use to_pci_dev() to get revision of PCI configuration.
V3:
If SCU00 is not unlocked, just enter its password again.
It is unnecessary to clear AHB lock condition and restore WDT default
setting again, before Fast-reset clearing.
V4:
repatch after "error : could not build fake ancestor" resolved.
V5:
Since CVE_2019_6260 item3, Most of AST2500 have disabled P2A(PCIe to AMBA).
However, for backward compatibility, some patches about P2A, such as items
of v5.2 and v5.3, are considered to be upstreamed with comments.
1. Add define macro to improve source readability.
ast_drv.h, ast_main.c, ast_post.c
2. Add comment about "Fast restet" is enabled for ARM-ICE debugger
ast_post.c
3. Add comment about Reset USB port to patch USB unknown device issue

drm: Initial KMS driver for AST (ASpeed Technologies) 2000 series (v2)
This is the initial driver for the Aspeed Technologies chips found in
servers. This driver supports the AST 2000, 2100, 2200, 2150 and 2300. It
doesn't support the AST11xx due to lack of hw to test it on, and them requiring
different codepaths.
This driver is intended to be used with xf86-video-modesetting in userspace.
This driver has a slightly different design than other KMS drivers, but
future server chips will probably share similiar setup. As these GPUs commonly
have low video RAM, it doesn't make sense to put the kms console in VRAM
always. This driver places the kms console into system RAM, and does dirty
updates to a copy in video RAM. When userspace sets a new scanout buffer,
it forcefully evicts the video RAM console, and X can create a framebuffer
that can use all of of video RAM.
This driver uses TTM but in a very simple fashion to control the eviction
to system RAM of the console, and multiple servers.
v2: add s/r support, fix Kconfig.

drm/ast: Disable fast reset after DRAM initial
[Bug][AST2500]
V1:
When AST2500 acts as stand-alone VGA so that DRAM and DVO initialization
have to be achieved by VGA driver with P2A (PCI to AHB) enabling.
However, HW suggests disable Fast reset mode after DRAM initializaton,
because fast reset mode is mainly designed for ARM ICE debugger.
Once Fast reset is checked as enabling, WDT (Watch Dog Timer) should be
first enabled to avoid system deadlock before disable fast reset mode.
V2:
Use to_pci_dev() to get revision of PCI configuration.
V3:
If SCU00 is not unlocked, just enter its password again.
It is unnecessary to clear AHB lock condition and restore WDT default
setting again, before Fast-reset clearing.
V4:
repatch after "error : could not build fake ancestor" resolved.
V5:
Since CVE_2019_6260 item3, Most of AST2500 have disabled P2A(PCIe to AMBA).
However, for backward compatibility, some patches about P2A, such as items
of v5.2 and v5.3, are considered to be upstreamed with comments.
1. Add define macro to improve source readability.

3. Add comment about Reset USB port to patch USB unknown device issue
