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>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2014-11-21fdt: Allow ft_board_setup() to report failureSimon Glass
This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

2014-07-22powerpc/mpc85xx: Check return value of find_tlb_idxYork Sun
find_tlb_idx() is called in board_early_init_r() on multiple boards. The return value is not checked before being used to disable a TLB. In normal case the return value wouldn't be -1. In case of a mis- configuration during porting to a new board, checking the return value may be helpful to reveal some user errors. Signed-off-by: York Sun <yorksun@freescale.com>

2012-04-24powerpc/85xx: don't display address map size (32-bit vs. 36-bit) during bootTimur Tabi
Most 85xx boards can be built as a 32-bit or a 36-bit. Current code sometimes displays which of these is actually built, but it's inconsistent. This is especially problematic since the "default" build for a given 85xx board can be either one, so if you don't see a message, you can't always know which size is being used. Not only that, but each board includes code that displays the message, so there is duplication. The 'bdinfo' command has been updated to display this information, so we don't need to display it at boot time. The board-specific code is deleted.

MPC8536 Rev 1.0 silicon have NMG_eSDHC118 erratum, so that the SDHC write protected pin polarity does not follow the SD card standard in MPC8536 Rev 1.0 silicon. The MPC8536DS board invert the SDHC_WP pin as a workaround.

2011-01-14mpc85xx boards: initdram() cleanup/bugfixBecky Bruce
Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-11-14mpc85xx: Fix SERDES/eTSEC message indentationPeter Tyser
Previously some mpc85xx boards printed indented messages such as the following on bootup: printf(" eTSEC4 is in sgmii mode.\n"); printf(" Serdes2 disalbed\n"); The bootup appearance looks cleaner if the indentation is removed which aligns these messages with other bootup output.

On the MPC85xx platform if we have SATA its connected on SERDES. Determing if SATA is enabled via sata_initialize should not be board specific and thus we move it out of the MPC8536DS board code. Additionally, now that we have is_serdes_configured() we can determine if the given SATA port is enabled and error out if its not in the driver. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2010-04-07fsl: improve the PIXIS code and fix a few bugsTimur Tabi
Refactor and document the Freescale PIXIS code, used on most 85xx and 86xx boards. This makes the code easier to read and more flexible. Delete pixis.h, because none of the exported functions were actually being used by any other file. Make all of the functions in pixis.c 'static'. Remove "#include pixis.h" from every file that has it. Remove some unnecessary #includes. Make 'pixis_base' into a macro, so that we don't need to define it in every function. Add "while(1);" loops at the end of functions that reset the board, so that execution doesn't continue while the reset is in progress. Replace in_8/out_8 calls with clrbits_8, setbits_8, or clrsetbits_8, where appropriate. Replace ulong/uint with their spelled-out equivalents. Remove unnecessary typecasts, changing the types of some variables if necessary. Add CONFIG_SYS_PIXIS_VCFGEN0_ENABLE and CONFIG_SYS_PIXIS_VBOOT_ENABLE to make it easier for specific boards to support variations in the PIXIS registers sets. No current boards appears to need this feature. Fix the definition of CONFIG_SYS_PIXIS_VBOOT_MASK for the MPC8610 HPCD. Apparently, "pixis_reset altbank" has never worked on this board.

2009-07-2285xx: Report which "bank" of NOR flash we are booting from on FSL boardsKumar Gala
The p2020DS, MPC8536DS, MPC8572DS, MPC8544DS boards are capable of swizzling the upper address bits of the NOR flash we boot out of which creates the concept of "virtual" banks. This is useful in that we can flash a test of image of u-boot and reset to one of the virtual banks while still maintaining a working image in "bank 0". The PIXIS FPGA exposes registers on LBC which we can use to determine which "bank" we are booting out of (as well as setting which bank to boot out of).
