* ARM: tegra: expand all SPL sizes to be consistentStephen Warren2015-10-021-1/+1
| | | | | | | | | | | | | | | | | | | | The size allocation for SPL is increased in all cases to match the already-expanded value used on Tegra124. This is both for general consistency, and because the seaboard build trips over the limit already when using one of the ARM compilers packaged with 14.04. For the record, when building Seaboard: arm-linux-gnueabi- SPL is too big by 0x36 bytes arm-linux-gnueabihf- SPL fits by 0x2a bytes arm-none-eabi- SPL fits by 0xa bytes (Those figures are from builds with the expanded SPL size allocation, relative to the non-expanded SPL size limit; they're better by about 6 bytes in the more constrained build.)

* ARM: tegra: CONFIG_{SYS_, }LOAD{_, }ADDR rationalizationStephen Warren2015-05-131-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As best I can tell, CONFIG_SYS_LOAD_ADDR and CONFIG_LOADADDR/$loadaddr serve essentially the same purpose. Roughly, if a command takes a load address, then CONFIG_SYS_LOAD_ADDR or $loadaddr (or both) are the default if the command-line does not specify the address. Different U-Boot commands are inconsistent re: which of the two default values they use. As such, set the two to the same value, and move the logic that does this into tegra-common-post.h so it's not duplicated. A number of other non- Tegra boards do this too. The values chosen for these macros are no longer consistent with anything in MEM_LAYOUT_ENV_SETTINGS. Regain consistency by setting $kernel_addr_r to CONFIG_LOADADDR. Older scripts tend to use $loadaddr for the default kernel load address, whereas newer scripts and features tend to use $kernel_addr_r, along with other variables for other purposes such as DTBs and initrds. Hence, it's logical they should share the same value. I had originally thought to make the $kernel_addr_r and CONFIG_LOADADDR have different values. This would guarantee no interference if a script used the two variables for different purposes. However, that scenario is unlikely given the semantic meaning associated with the two variables. The lowest available value is 0x90200000; see comments for MEM_LAYOUT_ENV_SETTINGS in tegra30-common-post.h for details. However, that value would be problematic for a script that loaded a raw zImage to $loadaddr, since it's more than 128MB beyond the start of SDRAM, which would interfere with the kernel's CONFIG_AUTO_ZRELADDR. So, let's not do that. The only potential fallout I could foresee from this patch is if someone has a script that loads the kernel to $loadaddr, but some other file (DTB, initrd) to a hard-coded address that the new value of $loadaddr interferes with. This seems unlikely. A user should not do that; they should either hard-code all load addresses, or use U-Boot-supplied variables for all load addresses. Equally, any fallout due to this change is trivial to fix; simply modify the load addresses in that script.

* dm: i2c: tegra: Convert to driver modelSimon Glass2014-12-111-3/+0
| | | | | | | | | | | | | | | | | | | | | | This converts all Tegra boards over to use driver model for I2C. The driver is adjusted to use driver model and the following obsolete CONFIGs are removed: - CONFIG_SYS_I2C_INIT_BOARD - CONFIG_I2C_MULTI_BUS - CONFIG_SYS_MAX_I2C_BUS - CONFIG_SYS_I2C_SPEED - CONFIG_SYS_I2C This has been tested on: - trimslice (no I2C) - beaver - Jetson-TK1 It has not been tested on Tegra 114 as I don't have that board.

| | | | | | | | | | | | Fix the timeout issue after running "bootp" command in u-boot console. For example you see "EHCI timed out on TD- token=0x...". TXFIFOTHRES bits of TXFILLTUNING register should be set to 0x10 after a controller reset and before RUN bit is set (per technical reference manual).

* ARM: tegra: Make cache line size SoC specificThierry Reding2013-08-191-0/+3
| | | | | | | | | | | | Currently all Tegra SoCs are assumed to have 32 byte cache lines. This isn't true for Tegra114, however, which uses 4 Cortex-A15 cores and therefore uses a cache line size of 64 bytes. Move the cache line size setting to the per-SoC common configuration file.

| | | | | | | | | | | | Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such, some CPU errata exist, and must be worked around. These must be worked around in the bootloader, since in general, the kernel (especially a multi-platform kernel) needs to support being launched in non-secure mode (normal world), and hence may not be able to write to the CP15 register to enable these workarounds.
