* Blackfin: bf533-stamp: rewrite resource swap logicMike Frysinger2009-01-28-24/+15
| | | | | | | The old swap function tended to clobber unrelated pins and screw up masks. Rewrite the thing from scratch so it only uses the resources it needs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bootldr: implement BF53x/BF56x LDR loaderMike Frysinger2009-01-28-13/+124
| | | | | | | The BF53x/BF56x parts do not have an on-chip ROM to boot LDRs out of arbitrary memory locations, so implement a basic one in software. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: implement real write support for OTPMike Frysinger2009-01-28-42/+115
| | | | | | | | Now that real documentation has been released for the OTP interface and the on-chip ROM wrt writing/timings, implement support for reading/writing as well as dumping/locking. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: update on-chip ROM APIMike Frysinger2009-01-28-40/+44
| | | | | | | This brings the API for the on-chip ROM in line with the toolchain and hardware documentation. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: allow serial console to be disabledMike Frysinger2009-01-28-0/+8
| | | | | | | Some devices have no UART device pulled out, so allow people to disable the driver completely in favor of other methods (like JTAG-console). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: support console-over-JTAGMike Frysinger2009-01-28-4/+136
| | | | | | | The Blackfin JTAG has the ability to pass data via a back-channel without halting the processor. Utilize that channel to emulate a console. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: handle new anomalies with resetMike Frysinger2009-01-28-5/+15
| | | | | | Workaround fun new anomalies related to software reset of the processor. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: pass RETX to LinuxMike Frysinger2009-01-28-1/+14
| | | | | | | Make sure we save the value of RETX at power on and then pass it on to the kernel so that it can nicely debug a "double-fault-caused-a-reset" crash. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: clarify relocation comment during initMike Frysinger2009-01-28-3/+7
| | | | | | | People often ask questions about the init process and when things go from flash to relocated base, so clarify the comments a bit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: just set SP register directly during initMike Frysinger2009-01-28-3/+2
| | | | | | | No need to set the SP register indirectly to the configured value when it can be set directly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: add portmuxing for UARTs on the BF51xMike Frysinger2009-01-28-1/+10
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: respect CONFIG_CLKIN_HALFMike Frysinger2009-01-28-1/+1
| | | | | | | | As pointed out by Ivan Koryakovskiy, the initialization code was not actually respecting the CONFIG_CLKIN_HALF option when configuring the PLL_CTL register. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: use common memcpy routine during initMike Frysinger2009-01-28-21/+11
| | | | | | | Rather than using a local custom memcpy function, just call the existing optimized Blackfin version. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: set default boot SPI CS for BF538/BF539Mike Frysinger2009-01-28-2/+2
| | | | | | | The BF538/BF539 use CS2 for booting off of rather than CS1 like newer Blackfin parts. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: punt unused BF533-STAMP definitionsMike Frysinger2009-01-28-3/+0
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: resurrect BF533-STAMP video splash driverMike Frysinger2009-01-28-4/+197
| | | | | | | This video driver used to live in the Blackfin cpu directory, but it was lost during the unification process. This brings it back. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: tighten up post memory coding styleMike Frysinger2009-01-28-12/+11
| | | | | | No functional changes here; just cleanup code style a bit. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf537-stamp nand: fix more style errors in previous commitMike Frysinger2009-01-28-3/+3
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: drop dead/wrong debug code in initdram()Mike Frysinger2009-01-28-49/+4
| | | | | | | The DEBUG code in initdram() is quite old and was never really useful, so just drop it altogether. Common Blackfin debug code does a better job. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bf533-ezkit: shuffle flash defines a littleMike Frysinger2009-01-28-9/+8
| | | | | | | | Some of the flash defines weren't in the correct location and caused build problems in some configurations, so let's move types and defines to better local locations. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: overhaul i2c driverMike Frysinger2009-01-28-470/+293
| | | | | | | | | | | The current Blackfin i2c driver does not work properly with certain devices due to it breaking up transfers incorrectly. This is a rewrite of the driver and relocates it to the newer place in the source tree. Also remove duplicated I2C speed defines in Blackfin board configs and disable I2C slave address usage since it isn't implemented. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: respect CONFIG_SYS_MONITOR_LEN for default flash protectionMike Frysinger2009-01-28-3/+3
| | | | | | | | Respect the CONFIG_SYS_MONITOR_LEN define rather than assuming a size of 128kB when setting up the default flash protection region for U-Boot itself. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: respect/check CONFIG_SYS_GBL_DATA_SIZEMike Frysinger2009-01-28-1/+5
| | | | | | | When setting up the global data, rather than relying on sizeof(), use the common CONFIG_SYS_GBL_DATA_SIZE define. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: implement general support for CONFIG_STATUS_LEDMike Frysinger2009-01-28-0/+13
| | | | | | Here are the Blackfin-specific and board-independent pieces for status leds. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: do not init i2c in Blackfin board initMike Frysinger2009-01-28-15/+0
| | | | | | | The common code takes care of calling i2c_init() when needed, so no point in us doing it as well. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: bfin_mac: update port muxingMike Frysinger2009-01-28-12/+35
| | | | | | Adds support more Blackfin parts and fixes broken muxing for older ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: fix dcache handling when doing dma memcpy'sMike Frysinger2009-01-28-7/+10
| | | | | | | | Our dcache invalidate function doesn't just invalidate, it also flushes. So rename the function accordingly and fix the dma_memcpy() function so it doesn't inadvertently corrupt the data destination. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* Blackfin: minimize time cache is turned off when replacing cplb entriesMike Frysinger2009-01-28-22/+9
| | | | Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: split cache handling out of dma_memcpy()Mike Frysinger2009-01-28-8/+17
| | | | | | | Creating a new dma_memcpy() function that skips all cache checks allows us to use the function in very early init where the cache is not yet setup. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Blackfin: abort dma_memcpy() for L1 scratchpadMike Frysinger2009-01-28-1/+12

* Blackfin: rename bootm.c to boot.cMike Frysinger2009-01-28-2/+2
| | | | | | | The boot file contains functions for more than just "bootm", so rename it accordingly. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* SATA: do not auto-initialize during bootMike Frysinger2009-01-27-24/+15
| | | | | | | | | | | | Rather than have the board code initialize SATA automatically during boot, make the user manually run "sata init". This brings the SATA subsystem in line with common U-Boot policy. Rather than having a dedicated weak function "is_sata_supported", people can override sata_initialize() to do their weird board stuff. Then they can call the actual __sata_initialize(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* part_efi: Fix partition size calculation due to inclusive ending LBA.Richard Retanubun2009-01-27-1/+3
| | | | | | | | | | The ending LBA is inclusive. Hence, the partition size should be ((ending-LBA + 1) - starting-LBA) to get the proper partition size. This is confirmed against the results from the parted tool. (e.g. use parted /dev/sda -s unit S print) and observe the size. Signed-off-by: Richard Retanubun <RichardRetanubun@RuggedCom.com>
* jffs2: Fix zero sector_size when not using CONFIG_JFFS2_CMDLINETomasz Figa2009-01-27-0/+92
| | | | | | | | | | | | | | | | This patch fixes a bug (?) introduced after inclusion of the new JFFS2 code. When not using CONFIG_JFFS2_CMDLINE, the code in cmd_jffs2.c doesn't fill in part->sector_size (keeping it as 0), but a correct value is needed by the code in jffs2_1pass.c. This causes all JFFS2 accesses to be in the same place of the memory, what obviously means impossibility to use the JFFS2 partition. This problem is fixed in this patch by including sector size calculation in non-CONFIG_JFFS2_CMDLINE mtdparts_init variant. Signed-off-by: Tomasz Figa <tomasz.figa_at_gmail.com>
* saveenv: standardize enablementMike Frysinger2009-01-27-18/+8
| | | | | | | | Rather than special casing each environment type for enabling the saveenv command, have them all behave the same. This avoids bitrot as new env sources are added/removed. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* soft_i2c.c add option for repeated start in i2c_read()Andrew Dyer2009-01-27-1/+20
| | | | | | | | | | | | | | | | This patch adds a #define to optionally change the behaviour of i2c_read() in soft_i2c.c to send an I2C repeated start instead of a stop-start between sending the device address pointer write and reading back the data. The current behaviour is retained as the default. While most devices will work either way, I have a smart battery(*) that requires repeated start, and someone at some point found a device that required a stop-start.
