From 871480933a1c28f8a9fed4c4d34d06c439a7a422 Mon Sep 17 00:00:00 2001 From: Srikant Patnaik Date: Sun, 11 Jan 2015 12:28:04 +0530 Subject: Moved, renamed, and deleted files The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure. --- ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S | 89 ----------------------- 1 file changed, 89 deletions(-) delete mode 100644 ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S (limited to 'ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S') diff --git a/ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S b/ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S deleted file mode 100644 index 2711d6d8..00000000 --- a/ANDROID_3.4.5/arch/unicore32/kernel/debug-macro.S +++ /dev/null @@ -1,89 +0,0 @@ -/* - * linux/arch/unicore32/kernel/debug-macro.S - * - * Code specific to PKUnity SoC and UniCore ISA - * - * Copyright (C) 2001-2010 GUAN Xue-tao - * - * This program is free software; you can redistribute it and/or modify - * it under the terms of the GNU General Public License version 2 as - * published by the Free Software Foundation. - * - * Debugging macro include header - */ -#include -#include - - .macro put_word_ocd, rd, rx=r16 -1001: movc \rx, p1.c0, #0 - cand.a \rx, #2 - bne 1001b - movc p1.c1, \rd, #1 - .endm - -#ifdef CONFIG_DEBUG_OCD - /* debug using UniCore On-Chip-Debugger */ - .macro addruart, rx - .endm - - .macro senduart, rd, rx - put_word_ocd \rd, \rx - .endm - - .macro busyuart, rd, rx - .endm - - .macro waituart, rd, rx - .endm -#else -#define UART_CLK_DEFAULT 3686400 * 20 - /* Uartclk = MCLK/ 2, The MCLK on my board is 3686400 * 40 */ -#define BAUD_RATE_DEFAULT 115200 - /* The baud rate of the serial port */ - -#define UART_DIVISOR_DEFAULT (UART_CLK_DEFAULT \ - / (16 * BAUD_RATE_DEFAULT) - 1) - - .macro addruart,rx - mrc p0, #0, \rx, c1, c0 - tst \rx, #1 @ MMU enabled? - moveq \rx, #0xee000000 @ physical base address - movne \rx, #0x6e000000 @ virtual address - - @ We probe for the active serial port here - @ However, now we assume UART0 is active: epip4d - @ We assume r1 and r2 can be clobbered. - - movl r2, #UART_DIVISOR_DEFAULT - mov r1, #0x80 - str r1, [\rx, #UART_LCR_OFFSET] - and r1, r2, #0xff00 - mov r1, r1, lsr #8 - str r1, [\rx, #UART_DLH_OFFSET] - and r1, r2, #0xff - str r1, [\rx, #UART_DLL_OFFSET] - mov r1, #0x7 - str r1, [\rx, #UART_FCR_OFFSET] - mov r1, #0x3 - str r1, [\rx, #UART_LCR_OFFSET] - mov r1, #0x0 - str r1, [\rx, #UART_IER_OFFSET] - .endm - - .macro senduart,rd,rx - str \rd, [\rx, #UART_THR_OFFSET] - .endm - - .macro waituart,rd,rx -1001: ldr \rd, [\rx, #UART_LSR_OFFSET] - tst \rd, #UART_LSR_THRE - beq 1001b - .endm - - .macro busyuart,rd,rx -1001: ldr \rd, [\rx, #UART_LSR_OFFSET] - tst \rd, #UART_LSR_TEMT - bne 1001b - .endm -#endif - -- cgit
