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.
great stuff!
With these patches applied, rk3188-rock still boots and the TPL has come down to 616byte on gcc-4.9 and 592bytes on gcc-6.3, so
Actually, after finding out that I should add a # CONFIG_TPL_DM_SERIAL is not set to my defconfig, the size goes down even more - to 488 bytes on both gcc-4.9 and gcc-6.3.
Still works and all.
OK great thanks for the report.

We have like vast amounts of free space in tpl now ;-)
I guess I should fold your TINY_MEMSET option into my rock board, once you've applied the core patch?
Heiko
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
