* kbuild: move asm-offsets.h rule to ./KbuildMasahiro Yamada2015-01-081-43/+0
| | | | | | | | | | | | | | | Currently, MIPS is the only architecture that needs include/generated/asm-offsets.h, but we have got ./Kbuild file now. It is a good reason to move asm-offsets.h rule from arch/mips/Makefile to ./Kbuild and add dummy asm-offsets.c for the other architectures. asm-offsets.h would be useful for all the architectures. This commit does not implement include/generated/bounds.h, but if necessary, it is easy to implement it.

| | | | | | | | Add intermediate .S files to .SECONDARY. Otherwise make deletes them and regenerates them each build. Also remove KBUILD_DTBS since the make system descends in dts/ anyway. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* MIPS: ath79: add tplink-mr3020 board supportAntony Pavlov2014-03-281-0/+1
| | | | | | | | | | | | | | | | This board support code can be used for TP-LINK WR703 too. TP-LINK WR703 is very similar to TP-LINK MR3020, there are some non-essential differences: * WR703 is smaller and cheaper; * WR703 has only one led, but MR3020 has five leds; * MR3020 uses mini-USB connector, WR703 uses micro-USB connector.

* MIPS: add pre-bootloader (pbl) image supportAntony Pavlov2012-12-141-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is based on ARM pbl support and allows creating a pre-bootloader binary for compressed image. For different MIPS SoCs (or even for different boards based on the same SoC) the operations carried on in start-pbl.S can be very different. The additional constraints can be imposed on the size of the boot code or the special magic labels in the beginning of the boot code; In some cases it could be necessary to show CPU is alive as early as possible (transmit a char via UART or blink a LED). So the demands for pbl start operation can be very different. E.g. malta board store boot code at the NOR flash mapped to the MIPS power-on address (0xbfc00000); it is the most simple case: we need just copy pbl image from direct-mapped flash to RAM and jump there. The XBurst-powered boards store boot code in the beginning of a NAND flash or in the beginning of SD/MMC card. In this case we must use simple and short NAND or SD/MMC access routines to copy pbl image to RAM. To meet so different demands a simple technique is selected: * MIPS pbl entry point located in file arch/mips/boot/start-pbl.S. * MIPS pbl code (see start-pbl.S) assumes that every pbl-enabled board has a arch/mips/boards/<BOARD>/include/board/board_pbl_start.h header file. This file must contain definition of the board_pbl_start macro. This macro is used as start of pbl image; * the most popular asm routines (stack setup, relocation to link address, NS16550 initialization (WIP) and so on) are containt in the arch/mips/include/asm/pbl_macros.h header file. So board pbl macro can use it if necessary. It is possible to create similar headers with macros for each specific SoC; so even if we have many different boards based on the same SoC the board_pbl_start macro for every board can be short and clear. * after board-specific initialization the stack pointer is initialized and pbl C code is started.

* Makefile: generate a barebox-flash-image linkSascha Hauer2012-08-121-2/+0
| | | | | | | | | | | | Depending on the SoC a barebox.bin, barebox.netx, barebox.s5p, MLO image is generated. With pbl support there now is an additional arch/arm/pbl/zbarebox.bin image. To help the user to determine which image should be flashed to his device, generate a barebox-flash-image link.
