* kconfig: move CONFIG_USE_PRIVATE_LIBGCC to KconfigMasahiro Yamada2014-10-23-0/+11
| | | | | | | | | | | | | | | The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86. Those architectures should "select" HAVE_PRIVATE_LIBGCC and CONFIG_USE_PRIVATE_LIBGCC should depend on it. Currently, this option is enabled on Tegra boards and x86 architecture. Move the definition from header files to Kconfig.

* kconfig: move CONFIG_SYS_HZ to lib/KconfigMasahiro Yamada2014-10-23-4/+8
| | | | | | | | | | | | CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h (but some boards still have redundant definitions). This commit moves the definition and the document in README to Kconfig. Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000, the sanity check in lib/time.c should be removed.

* lib: lmb: fix overflow in __lmb_alloc_base w/ large RAMStephen Warren2014-08-09-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | If a 32-bit system has 2GB of RAM, and the base address of that RAM is 2GB, then start+size will overflow a 32-bit value (to a value of 0). __lmb_alloc_base is affected by this; it calculates the minimum of (start+size of RAM) and max_addr. However, when start+size is 0, it is always less than max_addr, which causes the value of max_addr not to be taken into account when restricting the allocation's location. Fix this by calculating start+size separately, and if that calculation underflows, using -1 (interpreted as the max unsigned value) as the value instead, and then taking the min of that and max_addr. Now that start+size doesn't overflow, it's typically large, and max_addr dominates the min() call, and is taken into account. The user-visible symptom of this bug is that CONFIG_BOOTMAP_SZ is ignored on Tegra124 systems with 2GB of RAM, which in turn causes the DT to be relocated at the very end of RAM, which the ARM Linux kernel doesn't map during early boot, and which causes boot failures. With this fix, CONFIG_BOOTMAP_SZ correctly restricts the relocated DT to a much lower address, and everything works. Signed-off-by: Stephen Warren <swarren@nvidia.com>

* Implement generalised RSA public exponents for verified bootMichael van der Westhuizen2014-08-09-8/+145
| | | | | | | | | | | | | | | | | | | | | | | | Remove the verified boot limitation that only allows a single RSA public exponent of 65537 (F4). This change allows use with existing PKI infrastructure and has been tested with HSM-based PKI. Change the configuration OF tree format to store the RSA public exponent as a 64 bit integer and implement backward compatibility for verified boot configuration trees without this extra field. Parameterise vboot_test.sh to test different public exponents. Mathematics and other hard work by Andrew Bott.

* fdt: Add a function to get the alias sequence of a nodeSimon Glass2014-07-23-0/+46
| | | | | | | | | | | | | | | | | | | | Aliases are used to provide U-Boot's numbering of devices, such as: aliases { spi0 = "/spi@12330000"; } spi@12330000 { ... } This tells us that the SPI controller at 12330000 is considered to be the first SPI controller (SPI 0). So we have a numbering for the SPI node. Add a function that returns the numbering for a node assume that it exists in the list of aliases. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add a simple malloc() implementation for pre-relocationSimon Glass2014-07-23-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we are to have driver model before relocation we need to support some way of calling memory allocation routines. The standard malloc() is pretty complicated: 1. It uses some BSS memory for its state, and BSS is not available before relocation 2. It supports algorithms for reducing memory fragmentation and improving performace of free(). Before relocation we could happily just not support free(). 3. It includes about 4KB of code (Thumb 2) and 1KB of data. However since this has been loaded anyway this is not really a problem. The simplest way to support pre-relocation malloc() is to reserve an area of memory and allocate it in increasing blocks as needed. This implementation does this. To enable it, you need to define the size of the malloc() pool as described in the README. It will be located above the pre-relocation stack on supported architectures. Note that this implementation is only useful on machines which have some memory available before dram_init() is called - this includes those that do no DRAM init (like tegra) and those that do it in SPL (quite a few boards). Enabling driver model preior to relocation for the rest of the boards is left for a later exercise. Signed-off-by: Simon Glass <sjg@chromium.org>
* Add option -r to env import to allow import of text files with CRLF as line ↵Alexander Holler2014-07-22-1/+16
| | | | | | | | | | | | | | endings When this option is enabled, CRLF is treated like LF when importing environments from text files, which means CRs ('\r') in front of LFs ('\n') are just ignored. Drawback of enabling this option is that (maybe exported) variables which have a trailing CR in their content will get imported without that CR. But this drawback is very unlikely and the big advantage of letting Windows user create a *working* uEnv.txt too is likely more welcome. Signed-off-by: Alexander Holler <holler@ahsoftware.de>
