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>

Update the naming convention used in the network stack functions and variables that Ethernet drivers use to interact with it. This cleans up the temporary hacks that were added to this interface along with the DM support. This patch has a few remaining checkpatch.pl failures that would be out of the scope of this patch to fix (drivers that are in gross violation of checkpatch.pl).

2010-12-17ppc4xx/POST: Change ethernet test loop count to a default of 10Stefan Roese
This patch changes the PPC4xx ethernet POST loop test count from currently 192 (256 - 64) to a default of 10. While doing this the max frame size is increased. Each loop run uses a different frame size, starting with a max of 1514 bytes, down to 64. The default loop count of 10 can be overriden using CONFIG_SYS_POST_ETH_LOOPS in the board config header. The TEST_NUM loop has been removed as it was never used. The main reason for this change is to reduce the boot time on boards using this POST test, like the lwmon5 board. This change reduces the boot time by about 600ms on the lwmon5 board. Signed-off-by: Stefan Roese <sr@denx.de> Acked-by: Wolfgang Denk <wd@denx.de>
2010-11-28ppc4xx/POST: Handle cached SDRAM correctly in Denali (440EPx) ECC POSTStefan Roese
This patch fixes a problem in the Denali (440EPx) SDRAM ECC POST test. When cache is enabled in the SDRAM area, the values written to SDRAM need to be flushed from cache to SDRAM using the dcfb instruction. Without this patch the POST ECC test failed. Now its working again on platforms with cache enabled in SDRAM. Signed-off-by: Stefan Roese <sr@denx.de>
2010-11-17Switch from archive libraries to partial linkingSebastien Carlier
Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
2010-10-04ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese
This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch.

2010-09-23ppc4xx: POST UART: Use in/out_8() io-accessor functionsStefan Roese
This patch fixes a problem in the PPC4xx POST UART driver. This driver incorrectly used the in/out8() io-accessor functions. This could lead to problems since these functions don't guarantee execution ordering. This patch now replaces these functions with the correct ones. Additionally the driver is converted to using the NS16550 struct instead of macros for the register offsets. And some common code is factored out for better maintainability.

2009-09-11ppc4xx: Big cleanup of PPC4xx definesStefan Roese
This patch cleans up multiple issues of the 4xx register (mostly DCR, SDR, CPR, etc) definitions: - Change lower case defines to upper case (plb4_acr -> PLB4_ACR) - Change the defines to better match the names from the user's manuals (e.g. cprpllc -> CPR0_PLLC) - Removal of some unused defines Please test this patch intensive on your PPC4xx platform. Even though I tried not to break anything and tested successfully on multiple 4xx AMCC platforms, testing on custom platforms is recommended. Signed-off-by: Stefan Roese <sr@denx.de>

2008-01-16ppc4xx: Refactor ECC POST for AMCC Denali coreLarry Johnson
The ECC POST reported intermittent failures running after power-up on the Korat PPC440EPx board. Even when the test passed, the debugging output occasionally reported additional unexpected ECC errors. This refactoring has three main objectives: (1) minimize the code executed with ECC enabled during the tests, (2) add more checking of the results so any unexpected ECC errors would cause the test to fail, and (3) use synchronization (only) where required by the processor.

2007-12-27ppc4xx: Fix problem in 44x cache POST routineStefan Roese
As repoted by Larry Johnson, running "diag run cache" caused a crash in U-Boot. This problem was introduced by a patch that removed the TLB entry for the cache test after the test has completed. Since this TLB was only setup once, a 2nd attempt to run this cache test failed with a crash. Now this TLB entry is created every time the routine is called. Signed-off-by: Stefan Roese <sr@denx.de>
