common: Drop asm/global_data.h from common header

2021-02-02T20:33:42+00:00

Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include  at all, so
remove that include.

x86: Add support for more than 8 MTRRs

2020-09-25T03:27:27+00:00

At present the mtrr command only support 8 MTRRs. Some SoCs have more than
that. Update the implementation to support up to 10. Read the number of
MTRRs dynamically instead.

x86: hob: Try to show a name instead of a GUID

2020-09-25T03:27:27+00:00

GUIDs are one of the seven evils of the computer world. They obfuscate the
meaning and require people to look up long hex strings to decode it.

Luckily only a miniscule fraction of the 10^38 possible GUIDs are in use.

Add a way to decode the GUIDs known to U-Boot. Add a few more to the list
for good measure.

x86: mtrr: Fix parsing of "mtrr list" command

2020-09-01T05:24:45+00:00

The command 'mtrr' does not recognize the 'list' subcommand any more
since the code restructuring in commit b2a76b3fe75a ("x86: mtrr:
Restructure so command execution is in one place").

The if-else parsing the command arguments does not take 'list' into
account: the if-branch is intended for no subcommands, the else-branch
is intended for the non-list subcommands (which all expect additional
arguments). Calling the 'mtrr list' subcommand leads to a "return
CMD_RET_USAGE" in the else-branch.

Fix this by changing the else-branch to explicitly checking for
if (cmd != 'l').
