2014-02-07blackfin: Initialize the EMAC VLAN with proper default valueAaron Wu
EMAC_VLANx regs is not properly initiallized in u-boot, once it's overwrite in the kernel when DSA enabled, hot reset will lead to bringing up EMAC fail in u-boot. Signed-off-by: Aaron Wu <Aaron.Wu@analog.com> Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>

2013-12-13Makefile: use two double-quotations as a pairMasahiro Yamada
Some editors such as Emacs can highlight source files. But their parser algorithm is not perfect. If you use one double-quotation alone, some editor cannot handle it nicely and mark source lines as a string by mistake. It is preferable to use two double-quotations as a pair.

2013-07-31blackfin: Fix using gd->baudrate before setting its valueAxel Lin
Current code uses gd->baudrate before setting its value. Besides, I got below build warning which is introduced by commit ddb5c5be "blackfin: add baudrate to bdinfo". board.c:235:3: warning: passing argument 1 of 'simple_strtoul' makes pointer from integer without a cast [enabled by default] include/vsprintf.h:27:7: note: expected 'const char *' but argument is of type 'unsigned int' This patch ensures we get the baudrate setting before using it.

2013-07-31blackfin: gpio: Use proper mask for comparing functionAxel Lin
The function return from P_FUNCT2MUX(per) takes 2 bits, however for BF537_FAMILY with offset != 1 the function is 1 bit. Also has small refactor for better readability. In portmux_setup(), it looks odd having "muxreg &= ~(3 << 1);" while in current code we do muxreg |= (function << offset);. Signed-off-by: Axel Lin <axel.lin@ingics.com>

2013-05-13bfin: Move gpio support for bf54x and bf60x into the generic driver folder.Sonic Zhang
The gpio spec for bf54x and bf60x differ a lot from the old gpio driver for bf5xx. A lot of machine macros are used to accomodate both code in one gpio driver. This patch split the old gpio driver and move new gpio2 support to the generic gpio driver folder. - To enable gpio2 driver, macro CONFIG_ADI_GPIO2 should be defined in the board's config header file. - The gpio2 driver supports bf54x, bf60x and future ADI processors, while the older gpio driver supports bf50x, bf51x, bf52x, bf53x and bf561. - All blackfin specific gpio function names are replaced by the generic gpio APIs.

2013-05-13Blackfin: adjust asm constraints with NMI workaroundMike Frysinger
Newer gcc versions will sometimes use a Preg when "r" constraints, but that'll fail if we use an Ireg in the assignment. So force the code to always use a Dreg. This also fixes early boot crashes for older Blackfin parts when compiled with gcc-4.5. This version ends up selecting the same register for the input and output variables which corrupts the output assignment triggering an exception.

2013-04-01Consolidate bool typeYork Sun
'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files. Signed-off-by: York Sun <yorksun@freescale.com>

2013-03-15Introduce generic link section.h symbol filesSimon Glass
We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
