Subject: [meta-rockchip][PATCH v7 1/6] linux-yocto: add an initial NanoPi-M4 BSP
Date: Mon, 17 May 2021 14:19:33 +0200	[thread overview]
Message-ID: <20210517121938.207004-2-yann@blade-group.com> (raw)
In-Reply-To: <20210517121938.207004-1-yann@blade-group.com>

From: Yann Dirson <yann@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/board features are covered yet either (esp. Wifi/Bluetooth and
audio jack), and properly-woking HDMI still needs patches.

Tiny is not fully testable by itself, it can be minimally booted with
serial console (though still missing CONFIG_MULTIUSER for serial getty,
and CONFIG_INOTIFY_USER for proper udev operation) using:

 PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-tiny"
 KERNEL_FEATURES_append = "\
  ktypes/base/base.scc \
  features/debug/printk.scc \
  cfg/fs/ext4.scc \
  cfg/8250.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 using default configurations:
- standard                11MB
- tiny                     5MB
- tiny with no defconfig   2.5MB
