x86: Add support for more than 8 MTRRs

2020-09-25T03:27:27Z

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. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

x86: Allow showing details about a HOB entry

2020-09-25T03:27:27Z

Some HOBs include information that can be decoded. Add a -v option to the hob command, to allow this to be displayed. Add the ability to decode a resource descriptor. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

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

2020-09-25T03:27:27Z

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: hob: Add way to show a single hob entry

2020-09-25T03:27:26Z

The 'hob' command currently lists all HOB entries. Add way to list a single entry, by index. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

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

2020-09-01T05:24:45Z

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').

x86: mtrr: Enhance 'mtrr' command to list MTRRs on any CPU

2020-07-20T01:46:48Z

Update this command so it can list the MTRRs on a selected CPU. If '-c all' is used, then all CPUs are listed. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng Tested-by: Bin Meng

x86: mtrr: Update 'mtrr' to allow setting MTRRs on any CPU

Add a -c option to mtrr to allow any CPU to be updated with this command. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

x86: mtrr: Restructure so command execution is in one place

2020-07-20T01:46:48Z

At present do_mtrr() does the 'list' subcommand at the top and the rest below. Update it to do them all in the same place so we can (in a later patch) add parsing of the CPU number for all subcommands. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

x86: mtrr: Update the command to use the new mtrr calls

2020-07-20T01:46:47Z

Use the multi-CPU calls to set the MTRR values. This still supports only the boot CPU for now. Signed-off-by: Simon Glass Reviewed-by: Wolfgang Wallner Reviewed-by: Bin Meng

x86: mtrr: Add support for writing to MTRRs on any CPU

2020-07-20T01:46:47Z

To enable support for the 'mtrr' command, add a way to perform MTRR operations on selected CPUs. This works by setting up a little 'operation' structure and sending it around the CPUs for action. Signed-off-by: Simon Glass Reviewed-by: Bin Meng Reviewed-by: Wolfgang Wallner
