The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <trini@konsulko.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Enable support for PCI (Peripheral Interconnect Bus), a type of bus

used on some devices to allow the CPU to communicate with its

peripherals.

This subsystem requires driver model.

help
|
|
Enable compatibility functions for PCI so that old code can be used
|
|
with CONFIG_PCI enabled. This should be used as an interim
|
|
measure when porting a board to use driver model for PCI. Once the

|
board is fully supported, this option should be disabled.

the virtual memory base address to a physical address when adding the PCI
