* cfi_flash: Remove uneccessary #ifdef CONFIG_SYS_MAX_FLASH_BANKS_DETECTStefan Roese2010-09-20-9/+1
| | | | | | | Now that the defines are moved to header files we don't need this conditional compilation any more. Remove it. Signed-off-by: Stefan Roese <sr@denx.de>
* cfi_flash: Simplify dynamic flash bank number detectionStefan Roese2010-09-20-11/+4
| | | | | | | | | | | | | | | | | | | This patch simplifies the use of CONFIG_SYS_MAX_FLASH_BANKS_DETECT. By moving these optional variables and defines into the common code, board specific code is minimized. Currently only the following board use this feature: APC405, IDS8247, TQM834x And IDS8247 doesn't seem to really need this feature, since its not updating the bank number variable at all. So this patch removes the definition of CONFIG_SYS_MAX_FLASH_BANKS_DETECT from this board port. This new framework will be used by the upcoming lwmon5 update as well.

* cfi_flash: Add weak default for cfi_flash_bank_addr()Stefan Roese2010-09-20-4/+9
| | | | | | | | | | | cfi_flash_bank_addr(int bank_nr) returns the base addresses of the requested bank. Introducing this weak default enables boards to override this functions with a board specific version when required. This feature will be used in the lwmon5 board update, supporting runtime detection of 2 board revisions with different flash layouts. Signed-off-by: Stefan Roese <sr@denx.de>
* cfi_flash: Simplify flash_get_info()Stefan Roese2010-09-20-2/+2
| | | | | | | | | | This patch removes an unecessary check in the return statement. This is not needed, since "info" is initializes to NULL. And "info" will not be written to again, if the flash address is not found. Additionally "info" is not initialized to "0" but to "NULL". Signed-off-by: Stefan Roese <sr@denx.de>

* | Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips.Philippe De Muyter2010-08-18-8/+25

After some time :( searching for bugs in our board or soft, we have discovered that those chips have a small but annoying bug, documented in "Numonyx Axcell P33/P30 256-Mbit Specification Update" It states : When customer uses [...] block unlock, the block lock status might be altered inadvertently. Lock status might be set to either 01h or 03h unexpectedly (00h as expected data), which leads to program/erase failure on certain blocks. A working workaround is given, which I have applied and tested with success : Workaround: If the interval between 60h and its subsequent command can be guaranteed within 20us, Option I is recommended, otherwise Option II (involves hardware) should be selected. Option I: The table below lists the detail command sequences: Command Data bus Address bus Remarks Sequence 1 90h Block Address Read Lock Status 2 Read Block Address + 02h (2)(3) (1) 3 60h Block Address (2)(3) (1) Lock/Unlock/RCR Configuration 4 D0h/01h/03h Block Address Notes: (1) Block Address refers to RCR configuration data only when the 60h command sequence is used to set RCR register combined with 03h subsequent command. (2) For the third and fourth command sequences, the Block Address must be the same. (3) The interval between 60h command and its subsequent D0h/01h/2Fh/03h commands should be less than 20us. And here is a log comparison of a simple (destructive) flash test without and with the workaround. diff without-numonyx-workaround.log with-numonyx-workaround.log -U-Boot 2010.06-00696-g22b002c-dirty (Aug 16 2010 - 15:07:47) +U-Boot 2010.06-00696-g22b002c-dirty (Aug 16 2010 - 15:25:19) CPU: Freescale MCF5484 CPU CLK 200 MHz BUS CLK 100 MHz Board: Macq Electronique ME2060 I2C: ready DRAM: 64 MiB FLASH: 32 MiB In: serial Out: serial Err: serial Net: FEC0, FEC1 -> flinfo Bank # 1: CFI conformant FLASH (16 x 16) Size: 32 MB in 259 Sectors Intel Extended command set, Manufacturer ID: 0x89, Device ID: 0x8922 Erase timeout: 4096 ms, write timeout: 1 ms Buffer write timeout: 5 ms, buffer size: 1024 bytes Sector Start Addresses: FE000000 RO FE008000 RO FE010000 RO FE018000 RO FE020000 RO FE040000 RO FE060000 RO FE080000 RO FE0A0000 RO FE0C0000 RO ...

* | Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-1/+1
|/ | | | | | | | | | | | | | | | | | | While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>
* 83xx/85xx/86xx: LBC register cleanupBecky Bruce2010-07-16-11/+7
| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play. I have done a successful ppc build all and tested a board or two from each processor family.

* Blackfin: nand: drain the write buffer before returningAndrew Caldwell2010-05-26-1/+6
| | | | | | | | | | | | | The current Blackfin nand write function fills up the write buffer but returns before it has had a chance to drain. On faster systems, this isn't a problem as the operation finishes before the ECC registers are read, but on slower systems the ECC may be incomplete when the core tries to read it. So wait for the buffer to drain once we're done writing to it. Signed-off-by: Andrew Caldwell <Andrew.Caldwell@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* UBI: Ensure that "background thread" operations are really executedStefan Roese2010-05-19-2/+7
| | | | | | | | | | | | The current U-Boot UBI implementation is copied from Linux. In this porting the UBI background thread was not handled correctly. Upon write operations ubi_wl_flush() makes sure, that all queued operations, like page-erase, are completed. But this is missing for read operations. This patch now makes sure that such operations (like scrubbing upon bit-flip errors) are not queued, but executed directly. Signed-off-by: Stefan Roese <sr@denx.de>

* cfi_flash: reset timer in flash status checkThomas Chou2010-04-07-0/+2
| | | | | | | | | | | | | | | | | This patch adds reset_timer() before the flash status check waiting loop. Since the timer is basically running asynchronous to the cfi code, it is possible to call get_timer(0), then only a few _SYSCLK_ cycles later an interrupt is generated. This causes timeout even though much less time has elapsed. So the timer period registers should be reset before get_timer(0) is called. There is similar usage in nand_base.c.
