4 * @brief
5 * This is the sample OS Adaptation layer which is used by the UART
6 * driver. The OSAL layer can be ported in either of the following
7 * manners to a native OS:
8 *
9 * <b> Approach 1: </b>
10 * @n Use Prebuilt Libraries
11 * - Ensure that the provide an implementation of all
12 * Osal_XXX API for their native OS.
13 * - Link the prebuilt libraries with their application.
14 * - Refer to the "example" directory for an example of this
15 * @n <b> Pros: </b>
16 * - Customers can reuse prebuilt TI provided libraries
17 * @n <b> Cons: </b>
18 * - Level of indirection in the API to get to the actual OS call
19 *
20 * <b> Approach 2: </b>
21 * @n Rebuilt Library
22 * - Create a copy of this file and modify it to directly
23 * inline the native OS calls
24 * - Rebuild the UART Driver library; ensure that the Include
25 * path points to the directory where the copy of this file
26 * has been provided.
27 * - Please refer to the "test" directory for an example of this
28 * @n <b> Pros: </b>
29 * - Optimizations can be done to remove the level of indirection
30 * @n <b> Cons: </b>
31 * - UART Libraries need to be rebuilt by the customer.
