* nor/at91sam3: replace helper membufAntonio Borneo2010-06-171-87/+39
| | | | | | | | | | | | | Helper ./src/helper/membuf.c is only used in at91sam3.c 1) Replace membuf with LOG_* 2) The original code in sam3_GetDetails() invalidates all the buffered output of sam3_GetInfo(). The new code skips sam3_GetInfo() if its output should not be printed. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>

| | | | | | | | | | | when a write/unlock/erase failed during write_image, then an error was not propagated back up so e.g. flash write image from tcl scripts would not throw an exception.

| | | | | | | | | | | | | | Hello, "stm32x mass_erase" return ERROR_OK even if something goes wrong. Here is a summary of changes : * in stm32x_mass_erase : return ERROR_FLASH_OPERATION_FAILED when error detected in FLASH_SR register; * in COMMAND_HANDLER(stm32x_handle_mass_erase_command) : return the returned value of stm32x_mass_erase().

* nor: add get_flash_bank_by_name autoprobeSpencer Oliver2010-05-263-4/+32
| | | | | | | | | | | When a flash cmd is called using the flash name the autoprobe function is not called. autoprobe is called if flash_command_get_bank falls through to get_flash_bank_by_num. This makes both get_flash_bank_by_name and get_flash_bank_by_num behave the same. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* flash: add virtual flash bank driverSpencer Oliver2010-05-263-1/+248
| | | | | | | | | | | | | This adds a virtual flash bank driver that allows virtual banks to be defined that refer to an existing flash bank. For example the real address for bank0 on the pic32 is 0x1fc00000 but the user program will either be in kseg0 (0xbfc00000) or kseg1 (0x9fc00000). This also means that gdb will be aware of all the read only flash addresses. Signed-off-by: Spencer Oliver <ntfreak@users.sourceforge.net>
* NOR/CFI: fix memory leak; check malloc return valueAntonio Borneo2010-05-261-3/+48
| | | | | | | | | | | Every time command "flash probe #" is executed, memory structures are re-allocated without preventive free() of former areas, causing memory leak. Also, memory allocation does not check return value, determining segmentation fault in case of out of memory.

* nand : Add Freescale iMX27 nand flash controller supportgcembed2010-05-204-0/+900
| | | | | | | | This patch add support of iMX27 nand flash controller. This is based on driver for imx31 nand flash controller. OOB functionality is not fully working. As in mx31 controller, mx2 NFC has a bug that swap two bytes between SPARE and MAIN buffer. I used this driver for several months and no problems appear.
* NAND/davinci: Fix segfault for hwecc4_infix readsJon Povey2010-05-181-12/+62
| | | | | | | | | | | | | | | | | | | | Page reads using hwecc4_infix layout segfaulted for check_bad_blocks because the read assumed a valid data buffer, which check_bad_blocks does not use (it only passes a 6 byte buffer for the start of OOB). This version copes with undersized or missing data or oob buffers and uses random read commands within the page to skip unwanted areas of data/OOB for speed. NOTE: Running check_bad_blocks with this layout will be reading infix OOB locations, not manufacturer bad block markers. This means that if you check blocks written in infix layout they will appear good, but manufacturer- marked bad blocks may also appear good. If you want to scan for manufactuer-marked bad blocks, you need to enable raw_access before running check_bad_blocks, or use the non-infix layout.

* NAND: catch read errors when building BBTJon Povey2010-05-181-1/+4

* NOR/CFI: add cfi_read() implementationAntonio Borneo2010-05-161-2/+72
| | | | | | | | | | Final step to force bus_width size during CFI flash read. Added CFI specific implementation cfi_read() that uses only accesses at bus_width size. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR: add read() callback to struct flash_driverAntonio Borneo2010-05-1623-1/+72
| | | | | | | | | | | | | | Final target is to force bus_width size during CFI flash read. In this first step I need to replace default flash read with flash specific implementation. This patch introduces: - flash_driver_read() layer; - default_flash_read(), backward compatible; - read() callback in struct flash_driver; - proper initialization in every flash_driver instance.

* NOR/CFI: use bus_width for memory access in cfi_write()Antonio Borneo2010-05-161-54/+15
| | | | | | | | | | | | | | During cfi_write(), head and tail of destination area could be not aligned to bus_width. Since write operation must be at bus_width size, source buffer size is extended and buffer padded with current values read from flash. Force using bus_width to read current value from flash. Do not use cfi_add_byte() anymore, to allow removing this function later on. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: use bus_width for memory access on flash ID.Antonio Borneo2010-05-161-25/+22
| | | | | | | | | | NOR flash structure requires each access to be bus_width wide. Fix read of flash ID accordingly to rule above. Add case (chip_width == 4), allowed by CFI spec and coherent with current value of CFI_MAX_CHIP_WIDTH but currently not used by any target. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: identify memory accesses not using "bus_width".Antonio Borneo2010-05-161-0/+8
| | | | | | | | | | | | | | | | | | | | Since NOR flash devices does not handle "byte enable lanes", each read/write access involves the whole "chip_width". When multiple devices are in parallel, usually all chips are enabled during each access. All such cases are compatible with flash accesses at "bus_width" size. Access at "bus_width" size is mandatory for write access to avoid transferring of garbage values to flash. During read access the flash controller should take care, and discard unneeded bytes. Anyway, it is good practice to use "bus_width" size also for read. Every memory access that does not respect "bus_width" size is marked with a "FIXME" comment.

* NOR/CFI: simplify bufferwsize computationAntonio Borneo2010-05-161-39/+10
| | | | | | | | | | | | | | | | | | | | | | | | | Review and simplify computation of bufferwsize. Add comments about variables' meaning. The same code is present 3 times in the file. Current patch updates all the 3 instances. Step 1) Replace "switch(bank->chip_width) {...}". Illegal values of bank->chip_width are already dropped. For legal values, the code is equivalent to: bufferwsize = buffersize / bank->chip_width; Step 2) The above code replacement plus the following line: bufferwsize /= (bank->bus_width / bank->chip_width); is merged in a single formula: bufferwsize = (buffersize / bank->chip_width) / (bank->bus_width / bank->chip_width); and simplified as: bufferwsize = buffersize / bank->bus_width; Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com>
* NOR/CFI: check "flash bank" command argumentsAntonio Borneo2010-05-161-1/+11
| | | | | | | | | | | | | | | | | | Arguments chip_width and bus_width of command "flash bank" are not fully checked. While bus_width is later on redundantly checked in several other parts (e.g. in cfi_command_val()) and generates run-time error, chip_width is never checked, nor related to actual bus_width value. Added check to avoid: - (chip_width == 0), that would mean no memory chip at all, avoiding also division by zero e.g. in cfi_get_u8(); - (bus_width == 0), that would mean no bus at all; - unsupported cases of chip_width or bus_width value not power of 2; - unsupported case of chip width wider than bus.
