fastboot: add support for 'getvar platform'

2019-04-21T08:26:52+00:00

Our R-Car3 Android userspace relies on the output of 'fastboot
getvar platform' and U-Boot currently is not able to handle it:

host $> fastboot getvar platform
getvar:platform FAILED (remote: Variable not implemented)
finished. total time: 0.001s

We either have the option of adding 'fastboot.platform' variable
to the default/saved environment as a workaround or add proper
'fastboot getvar platform' support in U-Boot via this patch.
In the latter case, other platforms can benefit from it too.

Note that R-Car3 already exports 'platform' environment variable via
v2019.01 commit 00e4b57e9e71c3 ("ARM: rmobile: Set environment variable
containing CPU type").

fastboot: Replace literal 32 with PART_NAME_LEN

2019-04-21T08:26:52+00:00

Where we have to compute partition names, rather than using a hardcoded
32 for the partition name length, replace with PART_NAME_LEN.

fastboot: Improve error reporting on 'getvar partition-{size, type}'

2019-04-21T08:26:51+00:00

Currently U-Boot reports the same error message in all below cases:
[A] host> fastboot getvar partition-type
[B] host> fastboot getvar partition-size
[C] host> fastboot getvar partition-type:
[D] host> fastboot getvar partition-size:
[E] host> fastboot getvar partition-type:
[F] host> fastboot getvar partition-size:

The message looks like:
host> fastboot getvar partition-size:
getvar:partition-size: FAILED (remote: partition not found)
Finished. Total time: 0.003s

Be more user friendly and output:
 - "partition not given" for [A-D]
 - "partition not found" for [E-F]

fastboot: getvar: correct/rename "has_slot" to "has-slot"

2019-04-21T08:26:51+00:00

Since its inception in upstream fastboot android-n-preview-1 [1],
"has-slot" option has never taken the form of "has_slot". Amongst the
users of "getvar has-slot:" is the upstream bootloadertest.py [2].

Current U-Boot "has_slot" version must be a typo. Fix it.

fastboot: common: fix default fastboot_boot on 64-bit

2019-03-16T12:29:43+00:00

When booting on a 64-bit system, the boot_addr_start buffer is not
large enough to contain a 64-bit number, thus leading to a crash
even if fastboot_buf_addr is valid, only the high part of the address
will be printed to boot_addr_start :

fastboot with fastboot_buf_addr = 0x0000000006000000:
  downloading of 92239872 bytes finished
  Booting kernel at 0x00000000...

  "Synchronous Abort" handler, esr 0x96000004
  elr: 00000000010561f4 lr : 0000000001056fac (reloc)
  
  x28: 000000007df2d38f x29: 000000007df2d1b0

  Resetting CPU ...

With this fix, boot_addr_start can have the full 64-bit address passed
to bootm.
