[U-Boot] [PATCH v2 0/5] Patches to reduce TPL code size

[Simon Glass]

With the rockchip 'rock' board some build and code size problems have come
to light with TPL. This series provides a few ideas to improve things.

Changes in v2:
- Adjust the option to be SPL-only
- Change the option to default to off (name it CONFIG_SPL_TINY_MEMSET)
- Add a new patch to enable CONFIG_SPL_TINY_MEMSET
- Add new patch to allow driver model to be disabled for TPL
- Add new patch to allow driver-model serial to be disabled for TPL

Simon Glass (5):
  string: Provide a slimmed-down memset()
  rockchip: rock: Enable CONFIG_SPL_TINY_MEMSET
  Makefile: Provide an option to select SPL or TPL
  dm: core: Allow driver model to be disabled for TPL
  dm: serial: Allow driver-model serial to be disabled for TPL
