* blackfin: Fix using gd->baudrate before setting its valueAxel Lin2013-07-31-2/+1
| | | | | | | | | | | | | | 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.

* blackfin: gpio: Use proper mask for comparing functionAxel Lin2013-07-31-5/+6
| | | | | | | | | | | 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>

* bfin: Move gpio support for bf54x and bf60x into the generic driver folder.Sonic Zhang2013-05-13-183/+31
| | | | | | | | | | | | | | | 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.

* Blackfin: adjust asm constraints with NMI workaroundMike Frysinger2013-05-13-1/+2
| | | | | | | | | | | | | | | | | | | | | 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.

| * Refactor linker-generated arraysAlbert ARIBAUD2013-03-12-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor linker-generated array code so that symbols which were previously linker-generated are now compiler- generated. This causes relocation records of type R_ARM_ABS32 to become R_ARM_RELATIVE, which makes code which uses LGA able to run before relocation as well as after. Note: this affects more than ARM targets, as linker- lists span possibly all target architectures, notably PowerPC.

* | Introduce generic link section.h symbol filesSimon Glass2013-03-15-0/+27
|/ | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | Rework the emulation of serial console via JTAG from simple ad-hoc implementation of serial port routines to CONFIG_SERIAL_MULTI and enable CONFIG_SERIAL_MULTI unconditionally for blackfin. In order for the JTAG serial console to take precedence over all other serial ports available in system, implement override for default_serial_console call returning this JTAG serial console.
