2015-11-23lib/tiny-printf.c: Support numbers bigger than 0xffff and misc updatesStefan Roese
With this patch now, the tiny printf() function also supports numbers bigger than 0xffff. Additionally the code is simplified a bit and some static variables are moved to function parameters. Also the upper case hex variable output support is removed, as its not really needed in this simple printf version. And removing it reduces the complexity and the code size again a bit. Here the new numbers, again on the db-mv784mp-gp (Armada XP): Without this patch: 56542 18536 1956 77034 12cea ./spl/u-boot-spl With this patch: 56446 18536 1936 76918 12c76 ./spl/u-boot-spl Signed-off-by: Stefan Roese <sr@denx.de> Cc: Simon Glass <sjg@chromium.org> Cc: Hans de Goede <hdegoede@redhat.com> Cc: Tom Rini <trini@konsulko.com> Cc: Albert Aribaud <albert.u.boot@aribaud.net>
2015-11-23lib/tiny-printf.c: Add tiny printf function for space limited environmentsStefan Roese
This patch adds a small printf() version that supports all basic formats. Its intented to be used in U-Boot SPL versions on platforms with very limited internal RAM sizes. To enable it, just define CONFIG_USE_TINY_PRINTF in your defconfig. This will result in the SPL using this tiny function and the main U-Boot still using the full-blown printf() function. This code was copied from: http://www.sparetimelabs.com/printfrevisited With mostly only coding style related changes so that its checkpatch clean. The size reduction is about 2.5KiB. Here a comparison for the db-mv784mp-gp (Marvell AXP) SPL: Without this patch: 58963 18536 1928 79427 13643 ./spl/u-boot-spl With this patch: 56542 18536 1956 77034 12cea ./spl/u-boot-spl Note: To make it possible to compile tiny-printf.c instead of vsprintf.c when CONFIG_USE_TINY_PRINTF is defined, the functions printf() and vprintf() are moved from common/console.c into vsprintf.c in this patch.

2015-11-04dm: spl: Support device tree when BSS is in a different sectionSimon Glass
At present in SPL we place the device tree immediately after BSS. This avoids needing to copy it out of the way before BSS can be used. However on some boards BSS is not placed with the image - e.g. it can be in RAM if available. Add an option to tell U-Boot that the device tree should be placed at the end of the image binary (_image_binary_end) instead of at the end of BSS. Note: A common reason to place BSS in RAM is to support the FAT filesystem. We should update the code so that it does not use so much BSS.

2015-10-23fdt: fix fdtdec_get_pci_addr() for CONFIG_PHYS_64BITStephen Warren
PCI addresses are always represented as 3 cells in DT. (one cell for bus and device, and two cells for a 64-bit addres). This does not vary based on either the physical address size of the CPU, nor any #address-cells property in DT (or more precisely, #address-cells must be set to 3 in any PCIe controller's node).

2015-10-03fdtdec: fix parsing 'reg' property with zero value in '#size-cells'Przemyslaw Marczak
After rework of lib/fdtdec.c by: commit: 02464e3 fdt: add new fdt address parsing functions the function fdtdec_get_addr() doesn't work as previous, because the implementation assumes that properties '#address-cells' and '#size-cells' are equal to 1, which can be not true sometimes. The new API introduced fdtdec_get_addr_size_auto_parent() for the 'reg' property parsing, but the implementation assumes, that #size-cells can't be less than 1. This causes that the following children's 'reg' property can't be reached: parent@0x0 { #address-cells = <1>; #size-cells = <0>; children@0x100 { reg = < 0x100 >; }; }; Change the condition value from '1' to '0', which allows parsing property with at least zero #size-cells, fixes the issue. Now, fdtdec_get_addr_size_auto_parent() works properly. Tested on: Odroid U3/X2, Trats, Trats2, Odroid XU3, Snow (by Simon).

2015-10-03fdt: fix fdtdec_get_addr_size not to require any size cellsStephen Warren
fdtdec_get_addr_size() may be used in two cases: a) With sizep supplied, in which case both an address and a size are parsed from DT. In this case, the DT property must be large enough to contain both values. b) With sizep NULL, in which case only an address is parsed from DT. In this case, the DT property only need be large enough to contain this address value. Commit 02464e386bb5 "fdt: add new fdt address parsing functions" broke this relaxed checking, and required the DT property to contain both an address and a size value in all cases. Fix fdtdec_get_addr_size() to vary ns based on whether the size value is being parsed from the DT or not. This is safe since the function only parses the first entry in the property, so the overall value of (na + ns) need not be accurate, since it is never used to step through the property data to find other entries. Besides, this fixed behaviour essentially matches the original behaviour before the patch this patch fixes. (The original code validated that the property was exactly the length of either na or (na + ns), whereas the current code only validates that the property is at least that long. For non-failure cases, the two behaviours are identical).

2015-09-15env: import: hashtable: Prevent buffer overrun when importing environment ↵Lukasz Majewski
from file Lets consider following scenario: - One uses echo -n "key=value" to define environment variable in a file (single variable) - The file content is "key=value" without any terminating byte (e.g. 0x0a or 0x0d). - The file is loaded to u-boot non zero'ed RAM buffer (with load command). - Then "env import -t -r $loadaddr $filesize" is executed. - Due to lack of proper termination byte we have classical example of buffer overrun. This patch prevents from this by allocating one extra byte than size and explicitly null terminate it. There should be no change for normal env import operation after applying this patch.

2015-09-15fdt: add new fdt address parsing functionsStephen Warren
fdtdec_get_addr_size() hard-codes the number of cells used to represent an address or size in DT. This is incorrect in many cases depending on the DT binding for a particular node or property (e.g. it is incorrect for the "reg" property). In most cases, DT parsing code must use the properties #address-cells and #size-cells to parse addres properties. This change splits up the implementation of fdtdec_get_addr_size() so that the core logic can be used for both hard-coded and non-hard-coded cases. Various wrapper functions are implemented that support cases where hard-coded cell counts should or should not be used, and where the client does and doesn't know the parent node ID that contains the properties #address-cells and #size-cells. dev_get_addr() is updated to use the new functions. Core functionality in fdtdec_get_addr_size_fixed() is widely tested via fdtdec_get_addr_size(). I tested fdtdec_get_addr_size_auto_noparent() and dev_get_addr() by manually modifying the Tegra I2C driver to invoke them. Much of the core implementation of fdtdec_get_addr_size_fixed(), fdtdec_get_addr_size_auto_parent(), and fdtdec_get_addr_size_auto_noparent() comes from Thierry Reding's previous commit "fdt: Fix fdtdec_get_addr_size() for 64-bit".

Move malloc_cache_aligned() to a new header so that this can be avoided.
