2020-07-28find dtb in android boot image with header version 2 during bootmchenshuo
This patch is about bootm process, android boot image and device tree. Android 10 updates the boot image header to version 2, which includes a section to store the device tree blob (DTB) image. include/android_image.h has updated the struct andr_img_hdr, but not used in bootm process. This patch avoid reporting "Device tree not found or missing FDT support" when bootm a correctly constructed android boot image. Signed-off-by: chenshuo <chenshuo@eswin.com>

Platform code can call fdt_fixup_mtdparts() in order to hand U-Boot's MTD partitions over to the Linux device tree. Currently, fdt_fixup_mtdparts() calls mtdparts_init() in its entry.

This occurs when the same code (e.g. arch/arm/mach-uniphier/fdt-fixup.c) is shared among several boards, but not all of them support an MTD device. Parse the DT first, then call mtdparts_init() only when the target MTD node is found. Yet, you still need to call mtdparts_init() before device_find().

2020-07-24riscv: Make SiFive HiFive Unleashed board boot againBin Meng
Commit 40686c394e53 ("riscv: Clean up IPI initialization code") caused U-Boot failed to boot on SiFive HiFive Unleashed board. The codes inside arch_cpu_init_dm() may call U-Boot timer APIs before the call to riscv_init_ipi(). At that time the timer register base (e.g.: the SiFive CLINT device in this case) is unknown yet. It might be the name riscv_init_ipi() that misleads people to only consider it is related to IPI, but in fact the timer capability is provided by the same SiFive CLINT device that provides the IPI. Timer capability is needed for both UP and SMP. Considering that the original refactor does have benefits, that it makes the IPI code more similar to U-Boot initialization idioms. It also removes some quite ugly macros. Let's do the minimal revert instead of a complete revert, plus a fixes to arch_cpu_init_dm() to consider the SPL case.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-06-29spi: Convert CONFIG_DM_SPI* to CONFIG_$(SPL_TPL_)DM_SPI*Lukasz Majewski
This change allows more fine tuning of driver model based SPI support in SPL and TPL. It is now possible to explicitly enable/disable the DM_SPI support in SPL and TPL via Kconfig option. Before this change it was necessary to use: /* SPI Flash Configs */ #if defined(CONFIG_SPL_BUILD) #undef CONFIG_DM_SPI #undef CONFIG_DM_SPI_FLASH #undef CONFIG_SPI_FLASH_MTD #endif in the ./include/configs/<board>.h, which is error prone and shall be avoided when we strive to switch to Kconfig. The goal of this patch: Provide distinction for DM_SPI support in both U-Boot proper and SPL (TPL). Valid use case is when U-Boot proper wants to use DM_SPI, but SPL must still support non DM driver. Another use case is the conversion of non DM/DTS SPI driver to support DM/DTS. When such driver needs to work in both SPL and U-Boot proper, the distinction is needed in Kconfig (also if SPL version of the driver supports OF_PLATDATA). In the end of the day one would have to support following use cases (in single driver file - e.g. mxs_spi.c): - U-Boot proper driver supporting DT/DTS - U-Boot proper driver without DT/DTS support (deprecated) - SPL driver without DT/DTS support - SPL (and TPL) driver with DT/DTS (when the SoC has enough resources to run full blown DT/DTS) - SPL driver with DT/DTS and SPL_OF_PLATDATA (when one have constrained environment with no fitImage and OF_LIBFDT support). Some boards do require SPI support (with DM) in SPL (TPL) and some only have DM_SPI{_FLASH} defined to allow compiling SPL. This patch converts #ifdef CONFIG_DM_SPI* to #if CONFIG_IS_ENABLED(DM_SPI) and provides corresponding defines in Kconfig.

There is no technical reason to add additional 4k space for FDT. This space is completely unused and just increase memory requirements. This is problematic on systems with limited memory resources as Xilinx Zynq CSE/ZynqMP mini and Versal mini configurations. The patch is removing additional 4k space. EFI code is using copy_fdt() which copy FDT to different location. And all boot commands in case of using U-Boot's FDT pointed by $fdtcontroladdr are copying FDT to different locations by image_setup_libfdt(). That's why in proper flow none should modified DTB used by U-Boot that's why there is no need for additional space.
