From 374a0e306e05985a2b949713b2e80d60a6268395 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Fri, 16 Mar 2018 17:20:33 +0100 Subject: [PATCH] powerpc: mpc8xx: harmonise initialisation of the immap local pointer In most places, immap local pointer is defined as immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; In a few places, it is defined as immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); This patch replaces the few of the latest form by the other one. The two are fully equivalent since SPRN_IMMR is set with CONFIG_SYS_IMMR very early in start.S Signed-off-by: Christophe Leroy --- arch/powerpc/cpu/mpc8xx/cpu.c | 5 ++--- arch/powerpc/cpu/mpc8xx/speed.c | 3 +-- 2 files changed, 3 insertions(+), 5 deletions(-) diff --git a/arch/powerpc/cpu/mpc8xx/cpu.c b/arch/powerpc/cpu/mpc8xx/cpu.c index 1120fd7441..9da73ac22e 100644 --- a/arch/powerpc/cpu/mpc8xx/cpu.c +++ b/arch/powerpc/cpu/mpc8xx/cpu.c @@ -36,7 +36,7 @@ DECLARE_GLOBAL_DATA_PTR; static int check_CPU(long clock, uint pvr, uint immr) { - immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); + immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; uint k; char buf[32]; @@ -237,8 +237,7 @@ int do_reset(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) */ unsigned long get_tbclk(void) { - uint immr = get_immr(0); /* Return full IMMR contents */ - immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); + immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; ulong oscclk, factor, pll; if (in_be32(&immap->im_clkrst.car_sccr) & SCCR_TBS) diff --git a/arch/powerpc/cpu/mpc8xx/speed.c b/arch/powerpc/cpu/mpc8xx/speed.c index fa8f87cbc5..f8eb4a13ea 100644 --- a/arch/powerpc/cpu/mpc8xx/speed.c +++ b/arch/powerpc/cpu/mpc8xx/speed.c @@ -17,8 +17,7 @@ DECLARE_GLOBAL_DATA_PTR; */ int get_clocks(void) { - uint immr = get_immr(0); /* Return full IMMR contents */ - immap_t __iomem *immap = (immap_t __iomem *)(immr & 0xFFFF0000); + immap_t __iomem *immap = (immap_t __iomem *)CONFIG_SYS_IMMR; uint sccr = in_be32(&immap->im_clkrst.car_sccr); uint divider = 1 << (((sccr & SCCR_DFBRG11) >> 11) * 2); -- 2.39.5
