DDR address will -be decoded as row-bank-column instead of bank-row-column. -This will improve performance of serial data transfers. - -Refresh cycle value must be selected based on the frequency -of DDR. tREFI = 7.8 us as per JEDEC. The value for MDREF[REF_CNT] -should be based on round up (tREFI/tCK) formula. For 500MHz, mdref -value should be 0x0f3c8000. - -Signed-off-by: Calvin Johnson <calvin.johnson@nxp.com> ---- - board/freescale/ls1012afrdm/ls1012afrdm.c | 4 ++-- - board/freescale/ls1012aqds/ls1012aqds.c | 4 ++-- - board/freescale/ls1012ardb/ls1012ardb.c | 4 ++-- - 3 files changed, 6 insertions(+), 6 deletions(-) - -diff --git a/board/freescale/ls1012afrdm/ls1012afrdm.c b/board/freescale/ls1012afrdm/ls1012afrdm.c -index c691a76..4b7902a 100644 ---- a/board/freescale/ls1012afrdm/ls1012afrdm.c -+++ b/board/freescale/ls1012afrdm/ls1012afrdm.c -@@ -59,7 +59,7 @@ void mmdc_init(void) - out_be32(&mmdc->mdcfg2, 0x01ff00db); - - /* other parms */ -- out_be32(&mmdc->mdmisc, 0x00000680); -+ out_be32(&mmdc->mdmisc, 0x00001680); - out_be32(&mmdc->mpmur0, 0x00000800); - out_be32(&mmdc->mdrwd, 0x00002000); - out_be32(&mmdc->mpodtctrl, 0x0000022a); -@@ -118,7 +118,7 @@ void mmdc_init(void) - out_be32(&mmdc->mapsr, 0x00001067); - - /* refresh scheme */ -- set_wait_for_bits_clear(&mmdc->mdref, 0x103e8000, 0x00000001); -+ set_wait_for_bits_clear(&mmdc->mdref, 0x0f3c8000, 0x00000001); - - /* disable CON_REQ */ - out_be32(&mmdc->mdscr, 0x0); -diff --git a/board/freescale/ls1012aqds/ls1012aqds.c b/board/freescale/ls1012aqds/ls1012aqds.c -index 516f0c3..4ae8def 100644 ---- a/board/freescale/ls1012aqds/ls1012aqds.c -+++ b/board/freescale/ls1012aqds/ls1012aqds.c -@@ -82,7 +82,7 @@ void mmdc_init(void) - out_be32(&mmdc->mdcfg2, 0x01ff00db); - - /* other parms */ -- out_be32(&mmdc->mdmisc, 0x00000680); -+ out_be32(&mmdc->mdmisc, 0x00001680); - out_be32(&mmdc->mpmur0, 0x00000800); - out_be32(&mmdc->mdrwd, 0x00002000); - out_be32(&mmdc->mpodtctrl, 0x0000022a); -@@ -142,7 +142,7 @@ void mmdc_init(void) - out_be32(&mmdc->mapsr, 0x00001067); - - /* refresh scheme */ -- set_wait_for_bits_clear(&mmdc->mdref, 0x103e8000, 0x00000001); -+ set_wait_for_bits_clear(&mmdc->mdref, 0x0f3c8000, 0x00000001); - - /* disable CON_REQ */ - out_be32(&mmdc->mdscr, 0x0); -diff --git a/board/freescale/ls1012ardb/ls1012ardb.c b/board/freescale/ls1012ardb/ls1012ardb.c -index 7f7503c..06e1f6b 100644 ---- a/board/freescale/ls1012ardb/ls1012ardb.c -+++ b/board/freescale/ls1012ardb/ls1012ardb.c -@@ -88,7 +88,7 @@ void mmdc_init(void) - out_be32(&mmdc->mdcfg2, 0x01ff00db); - - /* other parms */ -- out_be32(&mmdc->mdmisc, 0x00000680); -+ out_be32(&mmdc->mdmisc, 0x00001680); - out_be32(&mmdc->mpmur0, 0x00000800); - out_be32(&mmdc->mdrwd, 0x00002000); - out_be32(&mmdc->mpodtctrl, 0x0000022a); -@@ -148,7 +148,7 @@ void mmdc_init(void) - out_be32(&mmdc->mapsr, 0x00001067); - - /* refresh scheme */ -- set_wait_for_bits_clear(&mmdc->mdref, 0x103e8000, 0x00000001); -+ set_wait_for_bits_clear(&mmdc->mdref, 0x0f3c8000, 0x00000001); - - /* disable CON_REQ */ - out_be32(&mmdc->mdscr, 0x0); --- -1.7.9.5 - |
