From d13ada11622977bcc0b530212b4405229805016d Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Wed, 6 Nov 2019 08:04:50 +1100 Subject: Add customisable EEPROM driver selection (#7274) - uprintf -> dprintf - Fix atsam "vendor" eeprom. - Bump Kinetis K20x to 64 bytes, too. - Rollback Kinetis to 32 bytes as partitioning can only be done once. Add warning about changing the value. - Change RAM-backed "fake" EEPROM implementations to match eeconfig's current usage. - Add 24LC128 by request. --- tmk_core/common/arm_atsam/eeprom.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) (limited to 'tmk_core/common/arm_atsam/eeprom.c') diff --git a/tmk_core/common/arm_atsam/eeprom.c b/tmk_core/common/arm_atsam/eeprom.c index 44a0bf4d76..a69f382823 100644 --- a/tmk_core/common/arm_atsam/eeprom.c +++ b/tmk_core/common/arm_atsam/eeprom.c @@ -16,9 +16,12 @@ #include "eeprom.h" -#define EEPROM_SIZE 32 +#ifndef EEPROM_SIZE +# include "eeconfig.h" +# define EEPROM_SIZE (((EECONFIG_SIZE+3)/4)*4) // based off eeconfig's current usage, aligned to 4-byte sizes, to deal with LTO +#endif -static uint8_t buffer[EEPROM_SIZE]; +__attribute__((aligned(4))) static uint8_t buffer[EEPROM_SIZE]; uint8_t eeprom_read_byte(const uint8_t *addr) { uintptr_t offset = (uintptr_t)addr; @@ -40,7 +43,7 @@ uint32_t eeprom_read_dword(const uint32_t *addr) { return eeprom_read_byte(p) | (eeprom_read_byte(p + 1) << 8) | (eeprom_read_byte(p + 2) << 16) | (eeprom_read_byte(p + 3) << 24); } -void eeprom_read_block(void *buf, const void *addr, uint32_t len) { +void eeprom_read_block(void *buf, const void *addr, size_t len) { const uint8_t *p = (const uint8_t *)addr; uint8_t * dest = (uint8_t *)buf; while (len--) { @@ -62,7 +65,7 @@ void eeprom_write_dword(uint32_t *addr, uint32_t value) { eeprom_write_byte(p, value >> 24); } -void eeprom_write_block(const void *buf, void *addr, uint32_t len) { +void eeprom_write_block(const void *buf, void *addr, size_t len) { uint8_t * p = (uint8_t *)addr; const uint8_t *src = (const uint8_t *)buf; while (len--) { @@ -86,7 +89,7 @@ void eeprom_update_dword(uint32_t *addr, uint32_t value) { eeprom_write_byte(p, value >> 24); } -void eeprom_update_block(const void *buf, void *addr, uint32_t len) { +void eeprom_update_block(const void *buf, void *addr, size_t len) { uint8_t * p = (uint8_t *)addr; const uint8_t *src = (const uint8_t *)buf; while (len--) { -- cgit v1.2.3
