From: Yann Dirson <y...@blade-group.com>
This patch provides "standard" and "tiny" BSP.
There is still much work to be done in dispatching feature to individual
scc files - the more boards we can support the better it will get.
Not all SoC features are covered yet either.
Tiny is not really testable by itself today, I played with it using:
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-tiny"
KERNEL_FEATURES_append = "\
ktypes/base/base.scc \
features/debug/printk.scc \
cfg/fs/ext4.scc \
"
Such a tiny build is still using mainline defconfig with lots of hardware
features, and the kernel can be slimmed down even more by using:
KBUILD_DEFCONFIG = ""
Kernel weight:
- standard 11MB
- tiny 5MB
- tiny with no defconfig 2.5MB
Changes in v2:
- added explicit CONFIG_PHYLIB and CONFIG_MMC to support empty defconfig
- added CONFIG_SPI_ROCKCHIP
