* Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips.Philippe De Muyter2010-08-18-8/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have "ported" U-boot to a in house made board with Numonyx Axcell P33/P30 256-Mbit 65nm flash chips. 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 ...

* cfi_flash: Cleanup flash_print_info()Stefan Roese2010-08-18-24/+27
| | | | | | | | | | | | | | | | | | | | | | | | | This patch does the following: - Extract code to detect if sector is erased into function sector_erased(). - Because of this, we don't have variable declarations inside the sector loop in flash_print_info() - Change "return" to "break" in the "if (ctrlc()) statement: This fixes a problem with the resulting output. Before this patch the output was: Sector Start Addresses: FC000000 FC020000 FC040000 => With this patch it is now: Sector Start Addresses: FC000000 FC020000 FC040000 => Signed-off-by: Stefan Roese <sr@denx.de> Cc: Kim Phillips <kim.phillips@freescale.com> Cc: Wolfgang Denk <wd@denx.de>

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>

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.
