* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-22-6/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* common: Add .u_boot_list into all linker filesMarek Vasut2012-10-22-0/+4
| | | | | | | | | | Add section for the linker-generated lists into all possible linker files, so that everyone can easily use these lists. This is mostly a mechanical adjustment.

* serial: Remove CONFIG_SERIAL_MULTI from remaining sourcesMarek Vasut2012-10-15-2/+0
| | | | | | | | | | | | Remove the parts depending either on disabled CONFIG_SERIAL_MULTI or ifdefs around CONFIG_SERIAL_MULTI parts since CONFIG_SERIAL_MULTI is now enabled by default.

* 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.

* serial: bfin: Adjust serial_register_bfin_uart()Marek Vasut2012-10-15-1/+1
| | | | | | | | | | | | Rename the serial_register_bfin_uart() to bfin_initialize_serial() to be consistent with the rest of the naming. Next, remove it's prototype from serial.h and properly insert it into serial.c as the rest of the serial initialization functions.

* serial: Rename .init() and .uninit() in serial_deviceMarek Vasut2012-10-15-2/+2
| | | | | | | | | | | | Rename .init() to .start() and .uninit() to .stop() in struct serial_device. This allows aligning struct serial_device with closer to struct stdio_dev. The real goal here is to allow these two structures to converge together and eventually make one to be a superset of the other.

* Consolidate bootcount code into drivers/bootcountStefan Roese2012-09-01-35/+0
| | | | | | | | | | | | | | | | | | | This patch moves all bootcount implementations into a common directory: drivers/bootcount. The generic bootcount driver is now usable not only by powerpc platforms, but others as well.

* global_data: unify global flag definesMike Frysinger2012-08-09-13/+1
| | | | | | | All the global flag defines are the same across all arches. So unify them in one place, and add a simple way for arches to extend for their needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: easylogo: add lzma logosMike Frysinger2012-02-03-0/+2898
| | | | | | | | | | The bf527-ezkit boards are getting too big to fit into their reserved flash space, so we need to use a lzma compressed logo. Since the video driver code is very similar, add lzma compressed support to all of the Blackfin video drivers. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* CONFIG_SYS_BAUDRATE_TABLE: Add <config_fallbacks.h>, place thereTom Rini2012-06-20-3/+0
| | | | | | | | | We provide a default table of { 9600, 19200, 38400, 57600, 115200 } in <config_fallbacks.h> which mkconfig places after <configs/...h> in the generated config file. This is used when a board has not set its own table. Signed-off-by: Tom Rini <trini@ti.com>
* net: move bootfile init into eth_initializeMike Frysinger2012-05-15-6/+1
| | | | | | | | All arches init this the same way, so move the logic into the core net code to avoid duplicating it everywhere else. Signed-off-by: Mike Frysinger <vapier@gentoo.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
* net: punt bd->bi_ip_addrMike Frysinger2012-05-15-4/+0
| | | | | | | | | This field gets read in one place (by "bdinfo"), and we can replace that with getenv("ipaddr"). After all, the bi_ip_addr field is kept up-to-date implicitly with the value of the ipaddr env var.

* Blackfin: move gd/bd to bss by defaultMike Frysinger2012-04-22-23/+43
| | | | | | | | We don't need these setup manually, so let the bss do the rest. On Blackfin systems, we clear the bss before executing any C code that would use these, so this should be fine. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: gd_t: relocate volatile markingsMike Frysinger2012-04-22-1/+1
| | | | | | | | | This makes Blackfin behave the same as other ports, and fixes many gcc warnings that show up with 4.5+: board.c:40:1: warning: optimization may eliminate reads and/or writes to register variables Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* POST: add post_log_res field for post results in global dataValentin Longchamp2011-10-05-0/+1
| | | | | | | | | | | | | | | | The current post_log_word in global data is currently split into 2x 16 bits: half for the test start, half for the test success. 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.

* console: Implement pre-console bufferGraeme Russ2011-10-05-0/+3
| | | | | | | | | | | | | Allow redirection of console output prior to console initialisation to a temporary buffer. To enable this functionality, the board (or arch) must define: - CONFIG_PRE_CONSOLE_BUFFER - Enable pre-console buffer - CONFIG_PRE_CON_BUF_ADDR - Base address of pre-console buffer - CONFIG_PRE_CON_BUF_SZ - Size of pre-console buffer (in bytes) The pre-console buffer will buffer the last CONFIG_PRE_CON_BUF_SZ bytes Any earlier characters are silently dropped.

| * Blackfin: serial: move early debug strings into .rodata sectionMike Frysinger2011-07-12-5/+5
| | | | | | | | | | | | | | | | | | | | Rewrite the assembly serial_early_puts() helper to place the strings in the .rodata section rather than embedding them directly in the .text section. Using .text is a little simpler, but it doesn't let people execute out of internal L1 sram (since core reads don't work on those regions). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: split out async setupMike Frysinger2011-07-12-50/+84
| | | | | | | | | | | | | | | | | | | | | | We really only need to tweak the async banks in the initcode if the processor is booting out of it, otherwise we can wait until later on in the CPU booting setup. This also makes testing in the sim and early bring up over JTAG work much smoother when the initcode gets bypassed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | | | | | | | | | | | | When we aren't doing resource tracking, the gpio_free() function is a stub that simply returns, so pull this logic up a level and make it an inline stub in the header.

| * Blackfin: add init.elf helper codeMike Frysinger2011-07-12-1/+43
| | | | | | | | | | | | | | | | | | This creates a standalone ELF that executes just the Blackfin initcode. This is useful for people who want to program the low level aspects of the CPU (memory/clocks/etc...) and can easily be used with JTAG for quick booting while developing.

| | | | | | | | | | | | | | | | | | | | | | | | This patch removes the architecture specific implementation of version_string where possible.
