From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bernhard Messerklinger Date: Mon, 18 May 2020 12:33:32 +0200 Subject: [PATCH v4 0/3] Move FSP configuration to devicetree Message-ID: <20200518103336.1097071-1-bernhard.messerklinger@br-automation.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This patch series moves the configuration of FPS-S and FSP-M for Apollo Lake based SoCs from the code to the devicetree. In order to make the FSP configuration easy to extend and maintain new binding structs for FSP-M and FSP-S are introduced. These structs contain the information of which devicetree settings need to be copied to which offset in the FSP config structure. The actual code handling these structs is rather small, and generic for both FSP-S and FSP-M. This patch series replaces the previous sent patches: "arch: x86: apl: Read FSP-M configuration from device-tree" [1] "Move FSP-S configuration to device-tree" [2] Changes to [1] and [2]: - No default settings within U-Boot, the default settings in FSP are used directly - The code for copying the data was simplified, and the information of what needs to be copied was moved to newly introduced structures [1]: https://lists.denx.de/pipermail/u-boot/2020-April/405852.html [2]: https://lists.denx.de/pipermail/u-boot/2020-April/406590.html Changes in v4: Fix comment alignment Changes in v3: Enable fspm,dual-rank-support-enable on chromebook coral Split patch into FSP-M and FSP-S Split patch into FSP-M and FSP-S Fix #if defined macro for FSP-S path to reduce SPL size Changes in v2: Integration of the review comments Fix swizzle size bug Bernhard Messerklinger (3): arch: x86: apl: Only load VBT if CONFIG_HAVE_VBT is enabled arch: x86: apl: Use devicetree for FSP-M configuration arch: x86: apl: Use devicetree for FSP-S configuration arch/x86/cpu/apollolake/Makefile | 1 + arch/x86/cpu/apollolake/fsp_bindings.c | 1803 +++++++++++++++++ arch/x86/cpu/apollolake/fsp_m.c | 169 +- arch/x86/cpu/apollolake/fsp_s.c | 430 +--- arch/x86/dts/chromebook_coral.dts | 73 +- .../asm/arch-apollolake/fsp/fsp_m_upd.h | 168 ++ .../asm/arch-apollolake/fsp/fsp_s_upd.h | 202 ++ .../asm/arch-apollolake/fsp_bindings.h | 110 + .../fsp/fsp2/apollolake/fsp-m.txt | 320 +++ .../fsp/fsp2/apollolake/fsp-s.txt | 483 +++++ 10 files changed, 3188 insertions(+), 571 deletions(-) create mode 100644 arch/x86/cpu/apollolake/fsp_bindings.c create mode 100644 arch/x86/include/asm/arch-apollolake/fsp_bindings.h create mode 100644 doc/device-tree-bindings/fsp/fsp2/apollolake/fsp-m.txt create mode 100644 doc/device-tree-bindings/fsp/fsp2/apollolake/fsp-s.txt -- 2.26.0
