+ Interface between kernel and boot loaders on Exynos boards
+ ==========================================================
+
+Author: Krzysztof Kozlowski
+Date : 6 June 2015
+
+The document tries to describe currently used interface between Linux kernel
+and boot loaders on Samsung Exynos based boards. This is not a definition
+of interface but rather a description of existing state, a reference
+for information purpose only.
+
+In the document "boot loader" means any of following: U-boot, proprietary
+SBOOT or any other firmware for ARMv7 and ARMv8 initializing the board before
+executing kernel.

+of the core. The internal powersave governor selects the appropriate P state

+Note that for Option 3, if the patch deviates from the original upstream patch
+(for example because it had to be backported) this must be very clearly
+documented and justified in the patch description.

+The upstream commit ID must be specified with a separate line above the commit

Additionally, some patches submitted via Option 1 may have additional patch
prerequisites which can be cherry-picked. This can be specified in the following

To submit firmware to that repository, please send either a git binary
diff or preferably a git pull request to:
- David Woodhouse <dwmw2@infradead.org>
- Ben Hutchings <ben@decadent.org.uk>
+ linux-firmware@kernel.org
+and also cc: to related mailing lists.
Your commit should include an update to the WHENCE file clearly
identifying the licence under which the firmware is available, and
that it is redistributable. If the licence is long and involved, it's
permitted to include it in a separate file and refer to it from the
WHENCE file.
+And if it were possible, a changelog of the firmware itself.
Ideally, your commit should contain a Signed-Off-By: from someone
authoritative on the licensing of the firmware in question (i.e. from
within the company that owns the code).
+
+
+WARNING:
+=======
+
+Don't send any "CONFIDENTIALITY STATEMENT" in your e-mail, patch or
+request. Otherwise your firmware _will never be accepted_.
+
+Maintainers are really busy, so don't expect a prompt reply.
