Initial documentation for TQMa6UL Yocto mirror project

Add comprehensive documentation for 2038-compliant BSP migration:

- README.md: Project overview, 2038 compliance verification
- 2038-problem-analysis.md: Detailed technical analysis confirming
  Scarthgap (5.0) provides 64-bit time_t on 32-bit ARM
- step-by-step-mirror-creation.md: Complete procedure for creating
  offline mirror on Ubuntu 22.04 outside corporate network
- license-compliance.md: License categories, approval criteria,
  and table templates for military use approval
- corporate-network-deployment.md: Installation and build setup
  for air-gapped corporate environment

Target: TQMa6UL-AB (i.MX6 UltraLite) on MBa6x
BSP: TQ scarthgap.TQ.ARM.BSP.0006
2038 Status: Verified compliant (kernel 6.6 + glibc 2.38+)

-Yocto BSP mirror for TQMa6UL with 2038 compliance and license analysis
+**Project ID:** TQMA6-YOCTO-2038  
+**Date:** 2026-03-01  
+**Target Hardware:** TQMa6UL-AB (i.MX6 UltraLite) on MBa6x Carrier  
+**Yocto Version:** Scarthgap (5.0) LTS  
+**Objective:** Create offline mirror for software approval, ensure 2038 compliance
+
+---
+
+## Overview
+
+This project addresses the requirement to migrate from legacy PTXdist-based BSP to Yocto Project for TQMa6UL hardware. The primary driver is Year 2038 compliance for military/long-term deployments.
+
+### 2038 Problem Context
+
+The Year 2038 Problem (Y2K38) affects 32-bit systems using signed 32-bit time_t:
+- Maximum representable time: 03:14:07 UTC on 19 January 2038
+- Systems will overflow and behave unpredictably after this date
+- Critical for military/aerospace systems with 15+ year service life
+
+### Solution: Yocto Scarthgap (5.0 LTS)
+
+**Key Features:**
+- 64-bit time_t by default on 32-bit ARM (glibc 2.38+)
+- Linux Kernel 6.6 LTS (includes CONFIG_COMPAT_32BIT_TIME)
+- Long-term support until April 2028 (extendable)
+- Full source availability for audit
+
+**2038 Compliance Verification:**
+| Component | Version | 2038 Ready | Notes |
+|-----------|---------|------------|-------|
+| Linux Kernel | 6.6.y | ✅ | CONFIG_COMPAT_32BIT_TIME |
+| glibc | 2.38+ | ✅ | 64-bit time_t default |
+| Yocto | 5.0 (Scarthgap) | ✅ | Built-in 2038 support |
+| TQ BSP | scarthgap.TQ.ARM.BSP.0006 | ✅ | Verified with kernel 6.6 |
