RC 1.4.11 (aws#464)

Release 1.4.11

* FPGA developer kit now supports Xilinx SDx/Vivado 2019.1
    * To upgrade, use Developer AMI v1.7.0 on the AWS Marketplace. The Developer Kit scripts (hdk_setup.sh or sdaccel_setup.sh) will detect the tool version and update the environment based on requirements needed for Xilinx 2019.1 tools.
* New functionality:
    * Added a developer resources section that provides guides on how to setup your own GUI Desktop and compute cluster environment.
    * Developers can now ask for AFI limit increases via the AWS Support Center Console
        * Create a case to increase your `EC2 FPGA` service limit from the console.
    * HLx IPI flow updates
        * HLx support for AXI Fast Memory mode.
        * HLx support for 3rd party simulations.
        * HLx support for changes in shell and AWS IP updates(e.g. sh_ddr).
* Bug Fixes:
    * Documentation fixes in the Shell Interface Specification
* Fixes for forum questions
        * Unable to compile aws_v1_0_vl_rfs.sv in Synopsys VCS
        * Use fpga_mgmt init in HLx runtime
    * New XRT versions added to the XRT Installation Instructions to fix segmentation faults when using xclbin instead of awsxclbin files.
* Deprecations:
    * Removed GUI Setup scripts from AMI v1.7.0 onwards.

Rc v1 4 10 (aws#463)

Release V1.4.10

* New functionality:
    * SDK now sorts the slots in DBDF order. Any scripts or integration maintainers should note that the slot order will be different from previous versions and should make any updates accordingly.

* Bug Fixes:
    * Fixes a bug in the [Automatic Traffic Generator (ATG)](./hdk/cl/examples/cl_dram_dma/design/cl_tst.sv). In SYNC mode, the ATG did not wait for write response transaction before issuing read transactions.
    * Released [Xilinx runtime(XRT) version 2018.3.3.2](https://github.com/Xilinx/XRT/releases/tag/2018.3.3.2) to fix the following error: `symbol lookup error: /opt/xilinx/xrt/lib/libxrt_aws.so: undefined symbol: uuid_parse!` discussed in this [forum post](https://forums.aws.amazon.com/thread.jspa?messageID=899474&#899474).
    * This release fixes a bug wherein concurrent AFI load requests on two or more slots resulted in a race condition which sometimes resulted in Error: `(20) pci-device-missing`
    * This release fixes a issue with coding style of logic which could infer a latch during synthesis in [sde_ps_acc module](./hdk/cl/examples/cl_sde/design/sde_ps_acc.sv) within cl_sde example

RELEASE V1.4.9

* New functionality:
    * Improved AFI load times for pipelined accelerator designs. For more details please see [Amazon FPGA image (AFI) pre-fetch and caching features](./hdk/docs/load_times.md).

 * Ease of Use features:
    * [Improved SDK Error messaging](./sdk/userspace/fpga_libs/fpga_mgmt/fpga_mgmt.c)
    * [Improved documentation](./hdk/docs/IPI_GUI_Vivado_Setup.md#switching-between-hdk-and-hlx-flows) to help with transition from [HLX to HDK command line flows](https://forums.aws.amazon.com/thread.jspa?threadID=302718&tstart=0) and vice versa
    * Incorporates feedback from [aws-fpga Issue 458](aws#458) by making the ```init_ddr``` function, used in design simulations to initialize DDR, more generic by moving out ATG deselection logic to a new ```deselect_atg_hw``` task

 * Bug Fixes:
    * Fixed Shell simulation model (sh_bfm) issue on PCIM AXI read data channel back pressure which was described in HDK 1.4.8 Errata.
    * Fixed HDK simulation example which [demonstrates DMA and PCIM traffic in parallel](./hdk/cl/examples/cl_dram_dma/verif/tests/test_dma_pcim_concurrent.sv).
