From 086f0c8e4f32ade9c80f2a8b2889ce870467c398 Mon Sep 17 00:00:00 2001 From: Edward O'Callaghan Date: Mon, 15 Nov 2021 15:47:15 +1100 Subject: flashrom: Drop read_flash_to_file() usage Aspire towards a goal of making cli_classic more of just a user of libflashrom than having quasi-parallel paths in flashrom.c This converts remaining read_flash_to_file() usage to the do_read() provider wrapper around libflashrom. BUG=b:208132085 TEST=` sudo ./flashrom -p ft2232_spi:type=232H,divisor=1000 -f -r out -c W25X05 Flashrom output: No EEPROM/flash device found. Force read (-f -r -c) requested, pretending the chip is there: Assuming Winbond flash chip "W25X05" (64 kB, SPI) on ft2232_spi. Please note that forced reads most likely contain garbage. Block protection could not be disabled! Reading flash... done.
