The official OpenEmbedded/Yocto BSP layer for Altera SoCFPGA platforms
This layer works with poky and Angstrom
Please follow the recommended setup procedures of your OE distribution.

Specifying Kernel Versions
==========================
This layer has a few providers for the kernel. These are the linux-altera,
linux-altera-ltsi, and linux-altera-ltsi-rt kernels. There are also
linux-altera-dev and linux-altera-ltsi-dev kernels which follow the current
development versions of those kernels.
To specify a linux-altera kernel, add the following to your conf/local.conf
PREFERRED_PROVIDER_virtual/kernel = "linux-altera"
PREFERRED_VERSION_linux-altera = "4.3%"
or for the linux-altera-ltsi kernel
PREFERRED_PROVIDER_virtual/kernel = "linux-altera-ltsi"
PREFERRED_VERSION_linux-alterai-ltsi = "3.10%"
Please note that older kernels will not compile with GCC 5+ and you will need
to specify in your conf/local.conf to revert to older 4.9 toolchain.
Specifying Toolchain Versions
=============================
The default Toolchain for ARM in Angstrom is the linaro toolchain. To specify
the use of this toolchain in Yocto add the following to conf/local.conf
GCCVERSION = "linaro-5.2"
SDKGCCVERSION = "linaro-5.2"
DEFAULTTUNE = "cortexa9hf-neon"
To use older kernels not supported by GCC 5+ you will need to use the 4.9 toolchain.
For Yocto:
GCCVERSION = "linaro-4.9"
SDKGCCVERSION = "linaro-4.9"
DEFAULTTUNE = "cortexa9hf-neon"
For Angstrom:
ANGSTROM_GCC_VERSION_arm = "linaro-4.9%"
