Make u-boot recognize full range of PPT LPC controllers

2012-03-29T22:01:28+00:00

The full range of LPC controllers should be accepted by u-boot when
looking for the SPI controller. The values come from Intel's
Panther_Point_EDS_v072.pdf (document #472178).

Reduce RW BIOS data sections to 512K from 976K

2012-03-16T18:24:50+00:00

This saves 500ms in the RW BIOS path and still leaves 130K
overhead from the current U-boot size (372K) which should be
more than enough for any future updates on stumpy/lumpy.

This should be re-visited if/when vboot is smart enough to
just read+validate the actual binary within the section.

2012-03-16T18:24:50+00:00

When U-boot is loaded via verified boot it starts at the

Use keyboard controller for hard reset instead of CF9

2012-03-16T06:35:02+00:00

For some still unknown reason writes to localtion 0xcf9 do not cause
the Link to reboot, they cause it to shut down instead. While this
will have to be investigated and fixed, this change modifies the code
to use the keyboard controller (implemented by the EC on Link) to
restart the system.

Once the 0xcf9 problem is resolved, this change could be reverted.

gen: Get disk/part_dos.c to compile when CONFIG_SYS_64BIT_LBA is turned on

2012-03-15T22:27:02+00:00

The code in this file tries to print an LBA using the format specifier
"%10ld", but when CONFIG_SYS_64BIT_LBA is turned on, the argument passed in
this position is a 64 bit value and isn't compatible. This change selects the
appropriate format specifier, the original or "10lld", based on whether
CONFIG_SYS_64BIT_LBA is turned on.
