Travis-CI is changing their support for FOSS (understandably) to have a
limited per-month number of build minutes.  Unfortunately for us, the
matrix of jobs we run will exhaust that very quickly.  Remove the yml
file.  Thanks for all the builds, Travis-CI!

Since linux commit 2e6cde96873253fd9eb0f20afd8ffd18278cff75 ("arm64:
dts: ls1028a: make the eMMC and SD card controllers use fixed indices")
mmc0 is the eMMC and mmc1 is the SD card. Also swap it in u-boot to
avoid any confusion by the user and to be aligned with linux.

Pull request for UEFI sub-system for efi-2021-01-rc4

* Provide a tool to create a file with UEFI variables to preseed UEFI
  variable store.
* Make size of UEFI variable store configurable.
* Add man pages for commands 'bootefi' and 'button'.

tools/efivar.py allows to prepare a file with UEFI variables to preseed
the UEFI variable store.

This script generates EFI variables for U-Boot variable store format.

A few examples:

  - Generating secure boot keys

    $ openssl req -x509 -sha256 -newkey rsa:2048 -subj /CN=TEST_PK/ \
            -keyout PK.key -out PK.crt -nodes -days 365
    $ efisiglist -a -c PK.crt -o foo.esl
    $ tools/efivar.py set -i ubootefi.var -n db -d foo.esl -t file
    $ tools/efivar.py set -i ubootefi.var -n kek -d foo.esl -t file
    $ tools/efivar.py set -i ubootefi.var -n pk -d foo.esl -t file

  - Printing out variables

    $ tools/efivar.py set -i ubootefi.var -n var1 -d foo -t str
    $ tools/efivar.py set -i ubootefi.var -n var2 -d bar -t str
    $ tools/efivar.py print -i ubootefi.var
    var1:
        8be4df61-93ca-11d2-aa0d-00e098032b8c EFI_GLOBAL_VARIABLE_GUID
        NV|BS|RT, DataSize = 0x3
        0000000000: 66 6F 6F                                          foo
    var2:
        8be4df61-93ca-11d2-aa0d-00e098032b8c EFI_GLOBAL_VARIABLE_GUID
        NV|BS|RT, DataSize = 0x3
        0000000000: 62 61 72                                          bar

    - Removing variables

      $ tools/efivar.py del -i ubootefi.var -n var1
      $ tools/efivar.py set -i ubootefi.var -n var1 -a nv,bs -d foo -t str
      $ tools/efivar.py print -i ubootefi.var -n var1
      var1:
          8be4df61-93ca-11d2-aa0d-00e098032b8c EFI_GLOBAL_VARIABLE_GUID
          NV|BS, DataSize = 0x3
          0000000000: 66 6F 6F                                        foo
      $ tools/efivar.py del -i ubootefi.var -n var1
      err: attributes don't match
      $ tools/efivar.py del -i ubootefi.var -n var1 -a nv,bs
      $ tools/efivar.py print -i ubootefi.var -n var1
      err: variable not found

Currently the size of the buffer to keep UEFI variables in memory is fixed
at 16384 bytes. This size has proven to be too small for some use cases.

Make the size of the memory buffer for UEFI variables customizable.
