* 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. P2 = 0xffe02008; /* EVT2 */ R0 = RETS; CALL 1f; RTN; 1: P2 = RETS; <-- BAD RETS = R0; [P2] = P2; <-- BAD Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>

* Consolidate bool typeYork Sun2013-04-01-3/+0
| | | | | | | | | | | | | '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.

| * 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>

* serial: bfin: Flip the jtag serial console to CONFIG_SERIAL_MULTIMarek Vasut2012-10-15-7/+30
| | | | | | | | | | | | | | | | | | | 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. This brings in a bit of a growth of size, but eventually will allow us to unconditionally enable CONFIG_SERIAL_MULTI throughout the whole U-Boot and maintain only one serial subsystem.

Since we alredy have more than 16 POST tests defined and more could be defined, this may result in an overflow and the post_output_backlog would not work for the tests defined further of these 16 positions. An additional field is added to global data so that we can now support up to 32 (depending of architecture) tests. The post_log_word is only used to record the start of the test and the new field post_log_res for the test success (or failure). The post_output_backlog is for this change also adapted.
