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>

Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it.

2018-12-15poplar: fix boot failure caused by serial driver changeShawn Guo
Commit 4687919684e0 ("serial: Remove DM_FLAG_PRE_RELOC flag in various drivers") essentially drops flag DM_FLAG_PRE_RELOC from serial_pl01x driver for Poplar platform, because the platform falls into the following strategy category made by the commit. Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for drivers that support both statically declared devices and configuration from device tree Before the commit lands, Poplar platform works by statically declaring pl011 serial device via U_BOOT_DEVICE() with DM_FLAG_PRE_RELOC flag set in the driver. But since Poplar also supports device configuration from device tree, the commit practically drops the flag for Poplar, and hence breaks the platform from booting. This patch changes platform code and device tree to initiate pl011 serial device from device tree rather than static declaration, so that above strategy about DM_FLAG_PRE_RELOC applies to Poplar, and therefore the reported boot failure gets fixed.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-03-16Convert all of CONFIG_CONS_INDEX to KconfigTom Rini
This converts the following to Kconfig: CONFIG_CONS_INDEX We have existing entries for this option in a number of places, with different guards on them. They're also sometimes used for things not directly inside of the serial driver. First, introduce a new symbol to guard the use of CONFIG_CONS_INDEX, so that in the case where we don't need this for the serial driver, but for some other use, we can still do it. Next, consolidate all of these into the single entry in drivers/serial/Kconfig. Finally, introduce CONS_INDEX_[023456] so that we can imply a correct value here to make the defconfig side of this smaller.

2016-04-25ARM: hisilicon: hikey: Align memory node with upstream kernelPeter Griffin
The memory node gets automatically generated by U-Boot in arch_fixup_fdt(), before passing control to the kernel using U-Boots representation of the dram banks. However the upstream kernel uses the memory node to carve-out regions of RAM for various purposes. To make this work without changing arch_fixup_fdt() which will effect many platforms we replicate the upstream memory node layout using the dram banks.

2015-09-28ARM: hikey: hi6220: Migrate over to DM_SERIAL and use UART3 by default.Peter Griffin
Use DM for the pl01x serial driver on hikey. Also allow UART0 or UART3 to be chosen via Kconfig. By default we now output to UART3 as the latest version of ATF outputs to this UART. Also UART3 comes out on the LS connector, as opposed to UART0 which goes to a unpopulated header. As part of this change we also enable CONFIG_BOARD_EARLY_INIT_F and call the pinmux configuration code for the UART. Before we were relying on ATF having already configured the pin configuration. NB: Upstream Linux kernel doesn't yet support UART3, so serial console will still be output on UART0 when booting a upstream kernel.

2015-08-12ARM64: hikey: hi6220: Add u-boot support for the 96boards CE HiKey board.Peter Griffin
HiKey is the first 96boards consumer edition compliant board. It features a hi6220 SoC which has eight ARM A53 cpu's. This initial port adds support for: - 1) Serial 2) eMMC / SD card 3) USB 4) GPIO It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable. Notes: eMMC has been tested with basic reading of eMMC partition into DDR. I have not tested writing / erasing. Due to lack of clock control it won't be running in the most performant high speed mode. SD card slot has been tested for reading and booting kernels into DDR. It is also currently configured to save the u-boot environment to the SD card. USB has been tested with ASIX networking adapter to tftpboot kernels into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage are correctly enumerated. GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.
