* treewide: replace '---help---' with 'help' in Kconfig filesMasahiro Yamada2019-05-171-1/+1
| | | | | | | | | | | | | | | | In Linux, '---help---' was deprecated in favor of 'help', and this is checked by the recent checkpatch.pl See Linux commit 84af7a6194e493fae312a2b7fa5a3b51f76d9282 The number of '---help---' is gradually decreasing in Linux, but there are still lots. However, '---help---' will be completely killed when the time comes. Fortunately, there are only some in Barebox. Replacing them is not hard.

* MIPS: relocation: add relocation supportOleksij Rempel2019-04-231-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch i a port of following patch from u-boot with some additional integration changes and fixes of original code: | Subject: [PATCH] MIPS: Stop building position independent code | | U-Boot has up until now built with -fpic for the MIPS architecture, | producing position independent code which uses indirection through a | global offset table, making relocation fairly straightforward as it | simply involves patching up GOT entries. | | Using -fpic does however have some downsides. The biggest of these is | that generated code is bloated in various ways. For example, function | calls are indirected through the GOT & the t9 register: | | 8f998064 lw t9,-32668(gp) | 0320f809 jalr t9 | | Without -fpic the call is simply: | | 0f803f01 jal be00fc04 <puts> | | This is more compact & faster (due to the lack of the load & the | dependency the jump has on its result). It is also easier to read & | debug because the disassembly shows what function is being called, | rather than just an offset from gp which would then have to be looked up | in the ELF to discover the target function. | | Another disadvantage of -fpic is that each function begins with a | sequence to calculate the value of the gp register, for example: | | 3c1c0004 lui gp,0x4 | 279c3384 addiu gp,gp,13188 | 0399e021 addu gp,gp,t9 | | Without using -fpic this sequence no longer appears at the start of each | function, reducing code size considerably. | | This patch switches U-Boot from building with -fpic to building with | -fno-pic, in order to gain the benefits described above. The cost of | this is an extra step during the build process to extract relocation | data from the ELF & write it into a new .rel section in a compact | format, plus the added complexity of dealing with multiple types of | relocation rather than the single type that applied to the GOT. The | benefit is smaller, cleaner, more debuggable code. The relocate_code() | function is reimplemented in C to handle the new relocation scheme, | which also makes it easier to read & debug. | | Taking maltael_defconfig as an example the size of u-boot.bin built | using the Codescape MIPS 2016.05-06 toolchain (gcc 4.9.2, binutils | 2.24.90) shrinks from 254KiB to 224KiB. | | Signed-off-by: Paul Burton <paul.burton@imgtec.com> Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* MIPS: pbl: add nmon MIPS nano-monitorAntony Pavlov2013-06-251-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nmon is a tiny monitor (<1200 bytes) program for the MIPS processors. It can operate with NO working RAM at all! It uses only the processor registers and NS16550-compatible UART port for operation, so it can be used for a memory controller setup code debugging. With no changes nmon should work on different MIPS processors as it uses only common MIPS-I instructions. nmon is inspired by mmon, MIPS VR4300 Mini-monitor. mmon is copyrighted 1996, 2003 by Eric Smith. Also Alexander Voropay must be noted for his work on qemu & YAMON mmon adaptations made in 2006 and 2007. See http://www.brouhaha.com/~eric/software/mmon/ for mmon details. The mmon's features missed in nmon: * batch memory dumps; * byte and 16-bit half-words dumps and stores; * fill memory; * load S-records (this function make sense only if RAM works properly). nmon has only 4 commands: q - quit to barebox d <addr> - read 32-bit word from <addr> address w <addr> <val> - write 32-bit word <val> to <addr> g <addr> - jump to <addr> Addresses and data must be given in hexadecimal. Everything (including hex digits 'a'..'f') must be in lower case. EXAMPLE: change value of word with address 0xa0000000 nmon> d a0000000 00000000 nmon> w a0000000 12345678 nmon> d a0000000 12345678 nmon> There is no error checking of any kind. If you give an invalid address you will probably get an exception which will hang the board and you will have to press the reset button. You can interrupt current command (e.g. you have made error in input <addr> value) by pressing the <ESC> key.
