We should not leave the expansion ROM address window open when there
is not a valid ROM.Suggested-by: Matt Porter
Signed-off-by: Bin Meng
Tested-by: Simon Glass
Acked-by: Simon Glass -
Currently PCI expansion ROM address is assigned by a call to
pciauto_setup_rom() outside of the pci auto config process.
This does not work when expansion ROM is on a device behind
PCI bridge where bridge's memory limit register was already
programmed to a value that does not cover the newly assigned
expansion ROM address. To fix this, we should configure the
ROM address during the auto config process.Signed-off-by: Bin Meng

This driver was originally added to support the native IDE mode for
Intel chipset, however it has some bugs like not supporting ATAPI
devices, endianness issue, or even broken build when CONFIG_LAB48.
Given no board is using this driver as of today, rather than fixing
all these issues we just remove it from the source tree.Signed-off-by: Bin Meng

On 32-bit machine strtol() returns LONG_MAX which is 0x7fffffff,
which is wrong for u-boot.rom components like u-boot-x86-16bit.bin.
Change to use strtoll() so that it works on both 32-bit and 64-bit
machines.Reported-by: Fei Wang

To try to reduce the pain of confusion of binary blobs, add MD5 checksums
for the current versions. This may worsen the situation as new versions
appear, but it should still be possible to obtain these versions, and thus
get a working setup.Signed-off-by: Simon Glass

Adjust minnowmax to use driver model for PCI. This requires adding a device

So far interrupt routing works pretty well for any on-chip devices
on Intel Crown Bay. When inserting any PCIe card to any PCIe slot,
Linux kernel is smart enough to do interrupt swizzling and figure
out device's irq using its parent bridge's interrupt routing info
all the way up to its root port. In U-Boot all PCIe root ports'
interrupts were routed to PIRQ E/F/G/H before, while actually all
PCIe downstream ports received INTx are routed to PIRQ A/B/C/D
directly and not configurable. Now we change this mapping so that
any external PCIe device can work correctly.Signed-off-by: Bin Meng

Document U-Boot multi-processor support as well as configuration

Acked-by: Simon Glass -
Implement write_mp_table() to create a minimal working MP table.
This includes an MP floating table, a configuration table header
and all of the 5 base configuration table entries. The I/O interrupt
assignment table entry is created based on the same information used
in the creation of PIRQ routing table from device tree. A check
duplicated entry logic is applied to prevent writing multiple I/O
interrupt entries with the same information.Use a Kconfig option GENERATE_MP_TABLE to tell U-Boot whether we
need actually write the MP table at the F seg, just like we did for
PIRQ routing and SFI tables. With MP table existence, linux kernel
will switch to I/O APIC and local APIC to process all the peripheral
interrupts instead of 8259 PICs. This takes full advantage of the
multicore hardware and the SMP kernel.Signed-off-by: Bin Meng

The MP table provides a way for the operating system to support
for symmetric multiprocessing as well as symmetric I/O interrupt
handling with the local APIC and I/O APIC. We provide a bunch of
APIs for U-Boot to write the floating table, configuration table
header as well as base and extended table entries.Signed-off-by: Bin Meng

There is no need to populate multiple irq info entries with the same
bus number and device number, but with different interrupt pin. We
