From 6ee37e28365f2a8ea498d03b08def0dcb1cc6494 Mon Sep 17 00:00:00 2001 From: Stefan Tauner Date: Sat, 29 Dec 2012 15:03:51 +0000 Subject: Improve SPI status register pretty printing - Move all functions related to SPI status registers to a new file spi25_statusreg.c. This includes the generic as well as the SST-specific functions from spi25.c and the chip-specific functions from a25.c and at25.c. - introduce helper functions * spi_prettyprint_status_register_hex() * spi_prettyprint_status_register_bpl() * spi_prettyprint_status_register_plain() Use the latter on every compatible flash chip that has no better printlock function set and get rid of the implicit pretty printing in the SPI probing functions. - remove * spi_prettyprint_status_register_common() * spi_prettyprint_status_register_amic_a25lq032() because it can be fully substituted with spi_prettyprint_status_register_amic_a25l032(). * spi_prettyprint_status_register() (old switch, no longer needed) - promote and export * spi_prettyprint_status_register_amic_a25l05p() as spi_prettyprint_status_register_default_bp1(). * spi_prettyprint_status_register_amic_a25l40p() as spi_prettyprint_status_register_default_bp2(). * spi_prettyprint_status_register_st_m25p() as spi_prettyprint_status_register_default_bp3(). - add #define TEST_BAD_REW and use it for a number of Atmel chips which had only TEST_BAD_READ set even though they dont have erasers or a write function set.
