From 57966101c827fcfa215aedee59f0e5aa558b7604 Mon Sep 17 00:00:00 2001 From: Liu Gang Date: Thu, 7 Mar 2013 22:41:02 +0000 Subject: powerpc/b4860qds: Add the tlb entries for SRIO interfaces Add the tlb entries based on the configuration of the SRIO interfaces. Every SRIO interface has 256M space: #define CONFIG_SYS_SRIO1_MEM_VIRT 0xa0000000 #define CONFIG_SYS_SRIO1_MEM_PHYS 0xc20000000ull #define CONFIG_SYS_SRIO2_MEM_VIRT 0xb0000000 #define CONFIG_SYS_SRIO2_MEM_PHYS 0xc30000000ull Signed-off-by: Liu Gang Signed-off-by: Andy Fleming --- board/freescale/b4860qds/tlb.c | 19 +++++++++++++++++-- 1 file changed, 17 insertions(+), 2 deletions(-) (limited to 'board/freescale/b4860qds') diff --git a/board/freescale/b4860qds/tlb.c b/board/freescale/b4860qds/tlb.c index 373cb78..6d634bf 100644 --- a/board/freescale/b4860qds/tlb.c +++ b/board/freescale/b4860qds/tlb.c @@ -111,8 +111,6 @@ struct fsl_e_tlb_entry tlb_table[] = { #ifdef CONFIG_SYS_NAND_BASE /* * *I*G - NAND - * entry 14 and 15 has been used hard coded, they will be disabled - * in cpu_init_f, so we use entry 16 for nand. */ SET_TLB_ENTRY(1, CONFIG_SYS_NAND_BASE, CONFIG_SYS_NAND_BASE_PHYS, MAS3_SX|MAS3_SW|MAS3_SR, MAS2_I|MAS2_G, @@ -122,6 +120,23 @@ struct fsl_e_tlb_entry tlb_table[] = { MAS3_SX|MAS3_SW|MAS3_SR, MAS2_I|MAS2_G, 0, 12, BOOKE_PAGESZ_4K, 1), + /* + * *I*G - SRIO + * entry 14 and 15 has been used hard coded, they will be disabled + * in cpu_init_f, so we use entry 16 for SRIO2. + */ +#ifdef CONFIG_SYS_SRIO1_MEM_PHYS + /* *I*G* - SRIO1 */ + SET_TLB_ENTRY(1, CONFIG_SYS_SRIO1_MEM_VIRT, CONFIG_SYS_SRIO1_MEM_PHYS, + MAS3_SW|MAS3_SR, MAS2_I|MAS2_G, + 0, 13, BOOKE_PAGESZ_256M, 1), +#endif +#ifdef CONFIG_SYS_SRIO2_MEM_PHYS + /* *I*G* - SRIO2 */ + SET_TLB_ENTRY(1, CONFIG_SYS_SRIO2_MEM_VIRT, CONFIG_SYS_SRIO2_MEM_PHYS, + MAS3_SW|MAS3_SR, MAS2_I|MAS2_G, + 0, 16, BOOKE_PAGESZ_256M, 1), +#endif }; int num_tlb_entries = ARRAY_SIZE(tlb_table); -- cgit v1.1
