[U-Boot] [PATCH v3 02/17] sf: Add bank address register reading support
by Jagannadha Sutradharudu Teki 13 Jun '13

13 Jun '13

This patch provides support to read a flash bank address register. reading extended/bank address register will give whether the flash is operated on extended/bank addressing or normal addressing in 3-byte address mode. Currently added an extended/bank address register reading support for spansion flashes. reff' the spec for more details about bank addr register in Page-63, Table 8.16 http://www.spansion.com/Support/Datasheets/S25FL128S_256S_00.pdf Signed-off-by: Jagannadha Sutradharudu Teki <jaganna(a)xilinx.com> --- Changes for v3: - none Changes for v2: - none drivers/mtd/spi/spi_flash.c | 15 +++++++++++++++ drivers/mtd/spi/spi_flash_internal.h | 4 ++++ 2 files changed, 19 insertions(+) diff --git a/drivers/mtd/spi/spi_flash.c b/drivers/mtd/spi/spi_flash.c index 7aba520..193de42 100644 --- a/drivers/mtd/spi/spi_flash.c +++ b/drivers/mtd/spi/spi_flash.c @@ -312,6 +312,21 @@ int spi_flash_cmd_bankaddr_write(struct spi_flash *flash, u8 bank_sel) return 0; } +int spi_flash_cmd_bankaddr_read(struct spi_flash *flash, void *data) +{ + u8 cmd; + u8 idcode0 = flash->idcode0; + + if (idcode0 == 0x01) { + cmd = CMD_BANKADDR_BRRD; + } else { + printf("SF: Unsupported bank addr read %02x\n", idcode0); + return -1; + } + + return spi_flash_read_common(flash, &cmd, 1, data, 1); +} + #ifdef CONFIG_OF_CONTROL int spi_flash_decode_fdt(const void *blob, struct spi_flash *flash) { diff --git a/drivers/mtd/spi/spi_flash_internal.h b/drivers/mtd/spi/spi_flash_internal.h index 6e38494..2567bbc 100644 --- a/drivers/mtd/spi/spi_flash_internal.h +++ b/drivers/mtd/spi/spi_flash_internal.h @@ -30,6 +30,7 @@ /* Bank addr acess commands */ #define CMD_BANKADDR_BRWR 0x17 +#define CMD_BANKADDR_BRRD 0x16 /* Common status */ #define STATUS_WIP 0x01 @@ -83,6 +84,9 @@ int spi_flash_cmd_write_status(struct spi_flash *flash, u8 sr); /* Program the bank address register */ int spi_flash_cmd_bankaddr_write(struct spi_flash *flash, u8 bank_sel); +/* Read the bank address register */ +int spi_flash_cmd_bankaddr_read(struct spi_flash *flash, void *data); + /* * Same as spi_flash_cmd_read() except it also claims/releases the SPI * bus.

[U-Boot] [PATCH v3 00/17] sf: Update sf framework to support all sizes of flashes
by Jagannadha Sutradharudu Teki 12 Jun '13

12 Jun '13

This series is v3 for the patch series sent few weeks back with a head "sf: Update sf framework to support all sizes of flashes" All patch are looks same for v2 and v3 but placed the bank addr code on CONFIG_SPI_FLASH_BAR to reduce the sizes. The current implementation in sf supports 3-byte address mode due to this up to 16MB amount of flash is able to access for those flashes which has an actual size of > 16MB. This series of patches is more detailed/meatured changes w.r.t the current sf framework in addition to changes related to support all sizes using bank/exnt register addr accessing support. With these new updates on sf framework, the flashes which has < 16MB are not effected as per as performance is concern and but the u-boot.bin size incrased ~600 bytes. sf update(for first 16MBytes), Changes before: U-Boot> sf update 0x1000000 0x0 0x1000000 - N25Q256 16777216 bytes written, 0 bytes skipped in 199.72s, speed 86480 B/s - W25Q128BV 16777216 bytes written, 0 bytes skipped in 351.739s, speed 48913 B/s - S25FL256S_64K 16777216 bytes written, 0 bytes skipped in 65.659s, speed 262144 B/s sf update(for first 16MBytes), Changes after: U-Boot> sf update 0x1000000 0x0 0x1000000 - N25Q256 16777216 bytes written, 0 bytes skipped in 198.953s, speed 86480 B/s - W25Q128BV 16777216 bytes written, 0 bytes skipped in 350.90s, speed 49200 B/s - S25FL256S_64K 16777216 bytes written, 0 bytes skipped in 66.521s, speed 262144 B/s The main aim of these changes is to not effect the current framework and at the same time to support the > 16Mbyte flashes, becuase of this I involved few flash vendor people in CC [thought that they may/mayn't be a mailing list members] to know their views.

[U-Boot] DHCP Gateway
by Saridakis, Dean (US SSA) 12 Jun '13

12 Jun '13

Is there a reason why the gateway address (NetOurGatewayIP) doesn't get set from the BOOTP header (bp_giaddr) as a default before processing the DHCP options? Sure would help me. Thanks, Dean
