From 2e91e8b3327015af4fc8b99bc81d9268a65eb559 Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 25 Feb 2021 17:22:39 +0800 Subject: [PATCH] ppc: qemu: Switch over to use DM serial The QEMU ppce500 target integrates 2 NS16550 serial ports. Switch over to use the DM version of the driver by: - drop unnecessary ad-hoc config macros - add get_serial_clock() in the board codes Signed-off-by: Bin Meng Reviewed-by: Simon Glass Reviewed-by: Priyanka Jain --- board/freescale/qemu-ppce500/qemu-ppce500.c | 6 ++++++ configs/qemu-ppce500_defconfig | 1 + include/configs/qemu-ppce500.h | 10 ---------- 3 files changed, 7 insertions(+), 10 deletions(-) diff --git a/board/freescale/qemu-ppce500/qemu-ppce500.c b/board/freescale/qemu-ppce500/qemu-ppce500.c index 50167d5..db13582 100644 --- a/board/freescale/qemu-ppce500/qemu-ppce500.c +++ b/board/freescale/qemu-ppce500/qemu-ppce500.c @@ -374,3 +374,9 @@ void *board_fdt_blob_setup(void) { return get_fdt_virt(); } + +/* See CONFIG_SYS_NS16550_CLK in arch/powerpc/include/asm/config.h */ +int get_serial_clock(void) +{ + return get_bus_freq(0); +} diff --git a/configs/qemu-ppce500_defconfig b/configs/qemu-ppce500_defconfig index f2a8b83..c528a68 100644 --- a/configs/qemu-ppce500_defconfig +++ b/configs/qemu-ppce500_defconfig @@ -30,6 +30,7 @@ CONFIG_SYS_RELOC_GD_ENV_ADDR=y CONFIG_DM=y # CONFIG_MMC is not set CONFIG_E1000=y +CONFIG_DM_SERIAL=y CONFIG_SYS_NS16550=y CONFIG_ADDR_MAP=y CONFIG_PANIC_HANG=y diff --git a/include/configs/qemu-ppce500.h b/include/configs/qemu-ppce500.h index f13e4ea..feac6ef 100644 --- a/include/configs/qemu-ppce500.h +++ b/include/configs/qemu-ppce500.h @@ -73,16 +73,6 @@ extern unsigned long long get_phys_ccsrbar_addr_early(void); #define CONFIG_SYS_MONITOR_LEN (512 * 1024) #define CONFIG_SYS_MALLOC_LEN (4 * 1024 * 1024) -#define CONFIG_SYS_NS16550_SERIAL -#define CONFIG_SYS_NS16550_REG_SIZE 1 -#define CONFIG_SYS_NS16550_CLK (get_bus_freq(0)) - -#define CONFIG_SYS_BAUDRATE_TABLE \ - {300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200} - -#define CONFIG_SYS_NS16550_COM1 (CONFIG_SYS_CCSRBAR+0x4500) -#define CONFIG_SYS_NS16550_COM2 (CONFIG_SYS_CCSRBAR+0x4600) - /* * General PCI * Memory space is mapped 1-1, but I/O space must start from 0. -- 2.7.4
