* ARM: zynq: add zynq fsbl checksum scriptSteffen Trumtrar2013-03-192-0/+73
| | | | | | | | | | | | The bootrom only reads an image if the correct checksum is present in the header. The calculation is pretty simple: sum over all words from 0x20 to 0x44 Two of this words are the image length. That is why the checksum can not be calculated until barebox_image_size is known. The easiest solution is a program that has to be run after make. Maybe this can be replaced with some linker-fu. Signed-off-by: Steffen Trumtrar <s.trumtrar@pengutronix.de>

* mtd: always write page when oob is givenSascha Hauer2013-03-031-1/+1
| | | | | | | | | | | | | Since recently we check for the page being written for not being empty and do not actually write it when it is. This fails for a freshly created flash bad block table when all blocks are good. In this case the bbt code will try to write an empty page, but with the BBT marker in OOB. This page never gets written, so the BBT code will not find a bad block table during next start up and writes it again. Fix this by checking if we want to write OOB data, if we do, then write the page, even if the data is empty. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * ARM i.MX35: Let MAX clk be in run-mode-onSascha Hauer2013-02-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The reset value for the MAX clk gate is 0b10, that is it is turned on in CPU run mode and off in stop mode. Configure it that way during startup. The 0b11 value previously in this field causes some nasty behaviour in the Linux kernel: - The i.MX35 has two bits per clock gate which are decoded as follows: 0b00 -> clock off 0b01 -> clock is on in run mode, off in wait/doze 0b10 -> clock is on in run/wait mode, off in doze 0b11 -> clock is always on The MAX clock is needed by the SoC, yet unused in the Kernel, so the common clock framework will disable it during late init time. It will only disable clocks though which it detects as being on. This detection is made depending on the lower bit of the gate. So with the value of 0b11 the clock framework will detect the clock as turned on, yet unused, hence it will turn it off and the system locks up. With the value of 0b10 instead, the clock framework will detect the clock as being disabled and will not try to turn it off, so the system works. The real bug is in the Linux clock framework. However, the value 0f 0b10 seems to be a sane default value, so restore it. This lets Linux work again and gives time to fix the bug in Linux. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM i.MX: Fix booting from NOR when external nand boot is enabledSascha Hauer2013-02-261-17/+29
| | | | | | | | | | | | | | | | | | | | We cannot jump to SDRAM unconditionally in imx*_barebox_boot_nand_external. When we really boot from NOR flash the binary is not yet copied to SDRAM. Instead, let the return value of imx_barebox_boot_nand_external() indicate whether we really boot from NAND and only jump to SDRAM in this case. Otherwise just continue to the normal SoC specific entry. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* arm: fix memset-related crashes caused by recent GCC (4.7.2) optimizationsIvan Djelic2013-02-151-41/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent GCC versions (e.g. GCC-4.7.2) perform optimizations based on assumptions about the implementation of memset and similar functions. The current ARM optimized memset code does not return the value of its first argument, as is usually expected from standard implementations. For instance in the following function: void debug_mutex_lock_common(struct mutex *lock, struct mutex_waiter *waiter) { memset(waiter, MUTEX_DEBUG_INIT, sizeof(*waiter)); waiter->magic = waiter; INIT_LIST_HEAD(&waiter->list); } compiled as: 800554d0 <debug_mutex_lock_common>: 800554d0: e92d4008 push {r3, lr} 800554d4: e1a00001 mov r0, r1 800554d8: e3a02010 mov r2, #16 ; 0x10 800554dc: e3a01011 mov r1, #17 ; 0x11 800554e0: eb04426e bl 80165ea0 <memset> 800554e4: e1a03000 mov r3, r0 800554e8: e583000c str r0, [r3, #12] 800554ec: e5830000 str r0, [r3] 800554f0: e5830004 str r0, [r3, #4] 800554f4: e8bd8008 pop {r3, pc} GCC assumes memset returns the value of pointer 'waiter' in register r0; causing register/memory corruptions. This patch fixes the return value of the assembly version of memset. Could you please review, or suggest better alternatives ? Thanks, -- Ivan (this is a shorter and (hopefully) clearer repost of http://lists.infradead.org/pipermail/linux-arm-kernel/2013-January/144916.html) The patch adds a 'mov' instruction and merges an additional load+store into existing load/store instructions. For ease of review, here is a breakdown of the patch into 4 simple steps: Step 1 ====== Perform the following substitutions: ip -> r8, then r0 -> ip, and insert 'mov ip, r0' as the first statement of the function. At this point, we have a memset() implementation returning the proper result, but corrupting r8 on some paths (the ones that were using ip). Step 2 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 1: save r8: - str lr, [sp, #-4]! + stmfd sp!, {r8, lr} and restore r8 on both exit paths: - ldmeqfd sp!, {pc} @ Now <64 bytes to go. + ldmeqfd sp!, {r8, pc} @ Now <64 bytes to go. (...) tst r2, #16 stmneia ip!, {r1, r3, r8, lr} - ldr lr, [sp], #4 + ldmfd sp!, {r8, lr} Step 3 ====== Make sure r8 is saved and restored when (! CALGN(1)+0) == 0: save r8: - stmfd sp!, {r4-r7, lr} + stmfd sp!, {r4-r8, lr} and restore r8 on both exit paths: bgt 3b - ldmeqfd sp!, {r4-r7, pc} + ldmeqfd sp!, {r4-r8, pc} (...) tst r2, #16 stmneia ip!, {r4-r7} - ldmfd sp!, {r4-r7, lr} + ldmfd sp!, {r4-r8, lr} Step 4 ====== Rewrite register list "r4-r7, r8" as "r4-r8".

| | | | | | | | | | | | The default setting for the imx28 watchdog is to do a power-off reset. If the SoC is only powered via battery, then the watchdog powers the chip down, though. According to the datasheet it should still be possible to execute a proper POR with battery power, but testing showed otherwise. When the watchdog power-off reset is disabled, a software reset is executed instead. This works with and without battery power.
