Say yes to expose VGA and LPC scratch registers, and other
miscellaneous control interfaces specific to the ASPEED BMC SoCs
config ASPEED_ESPI_SLAVE

Enable driver support for the Aspeed eSPI engine. Handles event
arising from firmware bootup and enable espi oob channel.
config ASPEED_LPC_CTRL
tristate "ASPEED LPC firmware cycle control"
select REGMAP
select MFD_SYSCON
default ARCH_ASPEED
help
Control LPC firmware cycle mappings through ioctl()s. The driver
also provides a read/write interface to a BMC ram region where the
host LPC read/write region can be buffered.
config ASPEED_LPC_MBOX
tristate "Aspeed LPC Mailbox Controller"
depends on REGMAP && MFD_SYSCON
help
Expose the ASPEED LPC MBOX registers found on Aspeed SOCs (AST2400
and AST2500) to userspace.
config ASPEED_LPC_SIO
tristate "Aspeed ast2400/2500 HOST LPC SIO support"

Provides a driver to control the LPC SIO interface on ASPEED platform
through ioctl()s.
config ASPEED_LPC_SNOOP
tristate "ASPEED LPC snoop support"
select REGMAP
select MFD_SYSCON
default ARCH_ASPEED
help
Provides a driver to control the LPC snoop interface which
allows the BMC to listen on and save the data written by
the host to an arbitrary LPC I/O port.
config ASPEED_MCTP
tristate "Aspeed ast2600 MCTP Controller support"
depends on REGMAP && MFD_SYSCON
help
Enable support for ast2600 MCTP Controller.
The MCTP controller allows the BMC to communicate with devices on
the host PCIe network.

help
Enable support for the XDMA Engine found on the ASPEED BMC
SoCs. The XDMA engine can perform PCIe DMA operations between the BMC
and a host processor.
config ASPEED_VGA_SHAREDMEM
tristate "Aspeed VGA Shared memory"
help
To access VGA shared memory on Aspeed BMC, enable this option.
This driver used by ManagedDataRegionlV2 specification. In the
specification, BIOS will transfer whole SMBIOS table to VGA memory,
and BMC can get the table from VGA memory through this driver.
